A lot.. Both of them.. But to simplify things, I'll brief some of their powers up..
Deathknight Arthas holds control over darkness, rituals, superhuman strength and endurance.. He can also animate dead and sacrefice undead to gain health himself.. He's somewhat faster than most humans and he regenerate health quickly.. He's advanced in swordfighting and holds a blade that rip energy out of a foe upon impact- which also grants him a great strategical mind ((which isn't actually his mind)) He can shoot dark magic on his foes.. He can raise already dead targets into indestructable soldiers and fight for him..
Illidan Stormrage, a demonhunter.. vast speed, endurance, stamina, agility ,accuracy, intelligence and strenght.. Got flight.. Can transform into a 30 feet demon with ranged abilities.. He can immolate anyone around him.. He can fire powerful beams out of his eyes.. He holds two magically enchanted blades, forged to destroy demons and dark entities.. He's vast in most human capabilites, except for sight.. He's blind.. At one point, he traded himself the power to read all magic.. He's pretty much magically omniscient.. All sources of magic can he read and understand.. He can launch fireballs, drain life-force, corrupt, launch balls of shadow and darkness, holds an aura that inflict damage to anyone near him.. He can summon demons.. He can create a parasite that infest anyone he choose.. which will devour them from the insied.. He automaticly reduce just aorund 60% of the health of his target.. He can drain the energy of your very soul and fill his life up..
Did I mention he flies?

Illidan is not a simple demon hunter, he is an empowered, demon with the powers of Kiljaeden, Sarg gave him his magic eyes and furthermore his own elven powers combined with the magic of the well of eternity, his magic powers far exceed Arthas, his two blades of azzinoth although each not the power of frostmourne but together and in his skillful hands, he could easily without being foolish give Arthas a run for his money, not to menstion he can fly, he could keep to the skies and laser beam arthas from all directions and Arthas would have few effective weapons to even harm Illidan, not to menstion his magic drain, he could drain arthas of his energies, burning the energies and harming arthas at the same time, Arthas both in canon and Illidan in canon at both their primes, Arthas would fall if Illidan went all out and bloodlusted taking into account abilities.
although you have a point that in canon, Arthas was weakened greatly, but i dont think this would be the deciding factor at all in this battle, what with Illidans obvious advantages.
I'm quite sure some of the more extreme powers you mention Illidan does not have at this stage. Main reasoning, why didn't Illidan do that when fighting him orginally
Arthas is not a namby-pamby paladin anymore. DeathKnights are alot more powerful than any Night Elf class/unit. Arthas is an exception DeathKnight at that. Deathcoil you see one shot people in cut scenes. Which is a more powerful spell than any i can think of Illidan posesses at this point.
theres nothing to assume he doesnt have them, just because he doesnt use them? its PIS, (plot induced stupidity) that he didnt use them, AND PIS that he didnt come from diffrent directions and didnt defend himself properly, his speed and powers are not neccerily going to be thwarted so easily in a true fight but the truth is AFAIK he has not gained any other major powers from beings or objects since, he doesnt just gain new ones like kain does over a period of time. His major powers come from aritfacts.
Death coil, ime not sure, cant remember when its been used and one-hit something in a cut-scene, what we know is that Illidan can summon through his blades the spirits of Azzinoth, can shoot lasers from his eyes and dark energy beams from his hands, and in demonic form can send forth blast waves of energy in large areas.
Also i was saying falses, Arthas is at full strength, if not stronger than usual when he faces Illidan, Lich king gives him what he could spare of his powers at the beginning of Synthony of forst and flame giving Arthas full strength once more and all his old powers, theres nothing to imply Arthas overcoming Illidan with anything, he simply wins through Illidans foolishness, the guy can fly, why hes flying at a level where he can be reached is beyond me, the guy definatley has some powers of his own, his powers are not even activated in the clip, his immolate for example, he has no powers on at all.
He doesn't have them in any part of the game until WoW.....so i am assuming he learns such things in OutLand.
Probably with this debate is that now Illidan is in WoW, it's claimable he knows all the things he has then, at the time he fought Arthas.
When Wrath of the Lich King comes out, i bet Arthas knew things he didn't use also, that he didn't gain from becoming the New Lich King.
An example of which is from the WoW game it's arguable that Kel'thuzard would destroy Arthas.
As much as you say Illidan lost due to PIS, Arthas would still have won, Death Coil is a more powerful spell than anything i recall Illidan having. Plus him losing in combat is adaquat proof in my eyes Arthas is a more skilled warrior in melee.
thats a fair enough assumption, but its not neccerily true, as i said PIS could be the reason, he did not use any of his abilities in that cinematic sequence and he didnt use many abilities, imagining he has learnt everything especially summoning the blades guardians i feel is a little weightless in the argument simply because its not something you could suddenly learn, not in the time hes beaten to the time hes in outland, illidan may have learnt some spells thats possible, but also his flight speed, we clearly see him moving in an instant what seems to be from the ground to the clouds in seconds. If his speed is that great, its far unlikely that that cinematic is showing what Illidan is truly capable of, the likelieness he has "leant" to move that fast is very low imo since surely you would agree, speed is not something you learn as such, not to that degree thats for sure.
ah but you see Arthas doesnt use his powers in that cinamatic either, which is odd, but Arthas is "supposed" to have new powers by many folds because he is the fusion now and is a near Godlike entity in a literal sense and he would be a God by Warcraft ruling if you accept the damned as his worshipers and the cults. But he has gained many levels of power so he has a reason to have new powers ,illidan on the other hand has not been shown or to have said to gain new abilities since his battle with Arthas, even though time has passed.
Seriously.. No skills, or flight, or strategical movements was used in the fight between Arthas and Illidan.. Have you seen Illidan fight? He's more badass than any Arthas around.. ((Excluding fusion))
And concerning Illidan's powers, he has them.. But he doesn't use them.. Why, I dont know, for he'd annhiliate Arthas in the battle for the frozen throne.. If you so strongly believe he got them after the battle of the frozen throne, tell me where.. Because of what I know about Illidan, he had those powers before WoW..
There's more to warcraft characters than what you meet in the campaign..
Do you think that Jaina could only use three spells? Water Elemental, Blizzard and Teleport? Do you think that the only thing Archimonde could do was summon units and turn people and buildings inside out? That Malfurion could only root his foes, summon living trees and heal the surrounding friendly units?

I saw that point of yours, but your looking at this fight as if it was all up to the in-game cinematic in the end of the Frozen Throne.. They fought hand-to-hand and Arthas won.. Not one single ability was used.. A demon-form Illidan is more badass than an Arthas ever will be ((Excluded fusion))
Take any fight.. The night elf demon hunter takes an undead death knight in melee several times over.. the demon hunter woop death knight ass in an original game..
And yes, I know that Arthas isn't an ordinarly death knight.. But do consider that Illidan is around 15000 or more years old, and he didn't exactly slack around while growing up.. He was the first, and is the strongest demon hunter of existance.. He is barely a demon hunter anymore.. He's a demon with elven blood.. He's a magiciant, a warrior, a demon hunter, a rogue, a bird and more combined..
Arthas.. a warrior with dark magic..

I dunno, see i think Illidan looks more badass that the new Lick but thats just IMO
No way, Deathknight Twaats a Demon Hunter, he just spams his range with death coil, after level 6 Demon hunter wins, but then you'll have an army with you by then so DK still wins in my book
Saying their not normal is kind of pointless because neither of them are ^^'
He had golden eyes didn't he?
The fact remain in combat, Arthas > Illidan, and thats how they both do things.
Death Coil is also superior to any spell in Illidans arsenal
No.. Hand-to-hand in a plot-based battle is where Arthas defeat Illidan.. And none of them used any ability.. If Illidan truly went all out, he'd be in Demon Form in the fight.. So, clearly he both held back and didn't do what it took to win..
And Mana Burn > Death Coil, in more than one way.. Especially like this.. Death Coil inflict damage, while Mana Burn drains the very energy of the being, as well as his health..

You are aware demon form is just a level 6 power used bacause of what happens to Illidan plot wise? it's not actually a seperate power. They kept it in TFT because it working in game.
Death Coil works on all beings, generally Death Coil > Manaburn. But i get your point. I can't recall which is which but I'm quite sure bana burn does different damage in the expainsion to the expansion....
