Yeah, I may have been overhyping the Emperor when I said he was on Odin's level. I still think that super high-end GEoM is (low) Skyfather tier, while maxwank (and I mean maxwank) is pretty much a casual universe-buster.
When it comes to his actual power level, AFAIK most of the Emperor's feats come from power-scaling using the Primarchs, high-end psykers, and Chaos Daemons. He's got some good feats (most of which are in the RT) but besides that he doesn't have much beyond power-scaling and some character statements.

LeGenD, combat feats for Valkorion that can contest packing the power of an exploding sun? Feats that match having the power to level entire planets with each blow?That is the God Emperor holding back by the way.
Hi there, I actually know stuff about the Emperor.
Physically the Emperor is around the level of his Primarchs. In terms of raw durability unaided by psychic ability, Konrad Curze, Primarch of the Night Lords, as a baby smashed into his planet of Nostramo and left a huge tear through the crust, which was heavily composed of Adamantium (one of the hardest metals in the setting). He was sent through the crust to the mantle itself. He proceeded to crawl out, once more, as a baby.
In terms of physical strength, the Primarchs can level mountains. Magnus recalls privately destroying mountain-tops while training with his brothers, Lion El'Jonson's fight with a Chaos-empowered Luther destroyed the fortress they were fighting in with the shockwaves of their blows (Lion isn't an active psyker, so this was pure strength). In general, Primarchs can physically wound each other with their blows, as can the Emperor. They can also all physically dismember Space Marines in terminator armour and powered armour. Some feats of these Marines include Space Marines surviving an arcane explosion in a great library (about the size of a large city) that engulfed all of it and incinerated the lesser-armoured guardsmen accompanying them. The Marines explicitly survived the psyflame, and were only killed by debris that collapsed on them from the explosion, being crushed under its weight in their armour. Marines also survived an orbital bombardment of barrage bombs on a city which leveled it and killed most of the demons and tyranids present. Both are from the fifth edition Grey Knights codex.
In terms of speed and reaction-time, a lowly space marine in Know No Fear could scope out the area and process a series of effective kill routes that he could take if shit went bad in a single nanosecond. Another marine runs an enemy through in an opening that lasted a single microsecond. Primarchs like Rogal Dorn, Konrad Curze, Angron, Lorgar, etc have been described as moving and fighting faster than a Space Marine can perceive.
The Emperor is mostly differentiated from his sons by his enormous psychic power. He is even more powerful than Magnus the Red and Lorgar, the first and second most powerful psykers among the primarchs. Magnus while fighting Leman Russ destroyed the surface of Prospero, he psychically afflicted a world with nightmares as a side effect of his power, he could incinerate towering Titans (it was 60+ meters tall and can withstand forces that can destabilize tectonic plates, like Deathstrike Missiles) with a hurricane of psyflame, etc. He's also explicitly the mightiest psyker in the setting. Some random villainous psyker named the Cacodominus who was killed by Black Templar marines was able to telepathically control 1,300 planetary systems with its power, but its psychic death scream was only a blip compared to the Astronomicon, which is powered by the Emperor's psychic power.
And yeah, the Emperor could psychically devastate the Realms of Chaos and is essentially a human Chaos God in terms of psychic might. As far as I'm aware no Star Wars character is nearly as powerful as him. But Odin? Odin could destroy the settings of both Star Wars and 40k with a single attack.
The emperor of mankind slaughters sidious and pretty much any other star wars character. Hell, Njal storm caller casually created a planetary storm that wiped out all life on the planet that he was fighting on and he isn't even considered to be on the emperor's level as far as psychers go. The emperor also beat horus after getting his through slit twice, his intestines pretty much hanging out, continuously losing blood, and suffering from multiple other injuries.
