Nihilus vs. Ancient Sith

I decided to say what the hell and asked Chris Avellone pretty Nihilus vs. Ancient Sith specifically Naga Sadow and got this

Hopefully you guys can see. If not he says Nihilus is indeed weaker than him/them.

Naga Sadow is the fifth strongest Sith Lord in my opinion, Nihilus is 11th. Right behind Freedon Nadd.

Yeah, I mean, that was literally said in the game, too.

Yeah but people argue different interpretations just like with everything else so it's good to have some sort of confirmation.

Nihilus is no match for some ancient Sith, he doesn’t just wreck them all, he would be defeated by tulak hord
