Woah! Kun>Nadd>Sadow>Palpatine.

If you go with hyperboles and writer wanking. Then, Kun>Vitiate(post-Nathema)

There is no hyperbole, your just in denial. You need help Nadd, it's unhealthy not being open to differing opinions.
You probably think, Nihilus would defeat GM luke in oneness with DE Sidious.
I assure you that I perceive Darth Nihilus as one of the most powerful beings to grace Star Wars mythos but I disagree with your line of thought.
We have indispensable proof of Darth Nihilus consuming moon-sized Katarr but we also noticed that Darth Nihilus was not able to consume Telos IV during the course of events in KoTOR II when he arrived there. Therefore, Darth Nihilus's powers are not limitless.
As the Exile recovered from this encounter, Kreia deliberately enticed the terrible Darth Nihilus to the planet Telos Four. Nihilus prepared to devour all life on the planet, and Nihilus's dreadnought, the Ravager, was met by the Republic Navy and Mandalorian forces. During the battle, the Exile boarded the Ravager and faced Nihilus. Unable to devour the Exile as he had so many others, Nihilus was finally defeated. With Telos safe, the Exile pursued Kreia.
- Taken from SWTOR
Secondly, Darth Nihilus's unique condition (an interplay of being a Wound in the Force and insatiable hunger) enabled him to employ Force Drain powers on a mass scale. A comparable analogy is Bastila Shan's affinity with Battle Meditation albeit natural.
However;
Bastila Shan < Revan
Darth Nihilus < Vitiate
Darth Nihilus didn't bother to advance the cause of Sith and showcased complete disregard for life. To him, appeasing his insatiable hunger was all that mattered. He didn't care about 'external threats' and/or attempts on his life, and he paid the price of his arrogance in the Battle of Telos IV consequently.
Vitiate was relatively a much more elusive and calculative individual. He went to great lengths to conceal himself and his Empire from the prying eyes of the Republic and the Jedi Order until the Great Galactic War; he did not had the luxury to devour worlds from time-to-time since he risked drawing attention and his adversaries would multiply. I suggest that you read/revisit Revan.
Anyhow, Vitiate was enhancing his strength/powers over time on a consistent basis by drawing energy from his subjects. Since he lasted much longer than Darth Nihilus, it isn't hard to believe that Vitiate surpassed Darth Nihilus in all respects eventually.
I get the impression that Darth Nihilus wasn't able to enhance his strength/powers on a consistent basis over time - his condition was getting the better of him instead and he was driven to consume on a mass-scale because he would self-destruct otherwise.
"There is no strength in the hunger he possesses… and the will behind his power is a primal thing. And it devours him as he devours others—his mere presence kills all around him, slowly, feeding him. He is already dead, it is simply a question of how many he kills before he falls." - Kriea

I get the impression that Ziost dwarfs Katarr in sheer size and significance. Ziost is recognized as one of the major population centers of the Empire and is physically large enough to have multiple moons.
Katarr looks really small from the views we have in Unseen, Unhead.
"darkest power in the galaxy"?
Kun's accolade-ic establishment over the ancient Sith?

Except that when it comes about your precious Valkorion, you highly overrate him and his accolades.
Katarr was not the only planet he consumed, though. So stop judging his power based on one consumed planet.
Where did you get that from? Really?
It was, in fact, stated that the more Nihilus drained, the greater his Hunger would become. His condition is not related to his ability to use a wide-planetary 'Force' drain. The more powerful he became, the more he had to drain. These two are mutable. He isn't that powerful because of his condition but because he drained a lot of worlds(which are rich in Force energy)
Except that Bastila's talent is 'normal' in terms of Force mastery. There are many Force users who are apt in some areas of the Force(for example Exar Kun in Sith sorcery)
1. Yes
2. No
Nihilus drained more worlds than Vitiate, so I would say he is more powerful than Vitiate.
Uh, yes, he did?
That's why he interfered in Onderon's political affairs.
Yes, he did, when he would be hungry. But Nihilus has shown concern for the Sith Order when he is fully fed. It wasn't arrogance that brought his fall, it was a blind trust in Tobin(Kreia's manipulation)
If he was stronger than Nihilus. He'd have shown himself to conquer the galaxy.
He could just drain unknown planets, you know...
Not that much of a boost. And he was using that boost to keep his immortality in check.
Except that he didn't. Whatever reasons you are looking for: Nihilus has shown capable to drain planets(and he drained more than Vitiate) That's a fact.
Whatever reason you are looking for Vitiate that he didn't/couldn't drain planets; it doesn't matter because he hasn't done. Simple as that.
His powers obviously increased. That's why he was able to drain so much Force energy from many planets. But he was using some of the energy he stole to sate his own Hunger.
Because Kreia has been with Nihilus for all their lives?
You do realize that Kreia only sees 'Force drain' in Nihilus? That's all. Anyways, by 'strength' she meant 'advantage'. And this is true because there is no advantage in having that hunger.
Just as Nihilus used some of his stolen power to appease his Hunger, Vitiate used that stolen power to keep his immortality in check.
However, people will use the Ziost's Dark Side nexus amplifying Vitiate's power. But that's irrelevant after draining Ziost because he got his 'lost-long' power back.
