It's from The Complete Star Wars Encyclopedia, not The Old Republic Encyclopedia.
Cool story, bro. What matters here is that Nihilus is a Sith Lord and nowhere in any official source is it suggested otherwise. Now try using less desperate methods to undermine Vitiate vis a vis Nihilus, k?
So back to what I said about no one in the Sith Empire caring who Nihilus is, which was my point. I never disagreed with Nihilus being a Sith to the Republic. Either way, Vitiate is stated to be more powerful than all other Force users, which is why I dropped it.
Why would I try to undermine Vitiate here? They're on teams. I want them to be the similar in power because I want to see the other combatants burn with a mere thought. Vitiate being more powerful than a person who ate a planet by speaking is even better. This thread was a gg before it was posted.
Vitiate should be above him based on his accolades, but Nihilus's planetary drain didn't require the aid of hundreds of sith lords, so he is better in that field. Though Nihilus may require some sort of prep (but to a lesser extent than Vitiate) to pull off his planetary drain, considering that a failed attempt on a single individual exhausted him considerably, which seems to suggest that even for him, utilizing drain instantly requires a tremendous amount of power to pull off.
As for their combat showings, Vitiate's defeat of the strike team is more impressive than anything Nihilus has done combat wise.
However, considering how much I dislike Vitiate, I have no problems with that notion, though.

I believe it does indeed have draw backs depending on how much of the drain he used in question and how much energy he receives in turn, he was already weakened when he faced the Exile, and he was actually exhausted by draining himself, not failing to drain the Exile. Apparently it rebounds of Force Wounds.
They stop at 2. Count Dooku and Anakin Skywalker have immunity to Drain like abilities and possess immense and unstoppable power respectively. Ulic Qel-Droma is not needed but he is a neat addition nonetheless and he have immunity to Drain like abilities too.
