Equally, those words of Uthar are subject to intense scrutiny. The opinion of an in-universe character about the relative power of another character from 1,000 years prior isn't exactly... conclusive.

Exactly. Sadow would have the best records, being 1k years before. Ajunta was 2k years before that, and Hord's unknown.
The only one who should have data similar in quality to Sadow is Ragnos.... and personally, I *would* find it easy to say Sadow is 'greater' even if he's less powerful, as Ragnos's 100 year term consisted merely of gobbling minor worlds, while Sadow took war to the core of the Republic.
(though by the same logic, one could point out how Ragnos expanded the Sith Empire, while it was destroyed under Sadow's watch)
They were sith empire sith, but the *original* sith were twelve Dark Jedi from the Hundred Years darkness.
Ajunta Pall, Karness Muur, XoXaan, Remulus Dreypa, and Sorzus Syn were the five greatest of the twelve, the others merely being Dark Jedi who were notable just for surviving the Hundred Year's Darkness, while those five were the leaders and greatest of them.
Ajunta was their leader and strongest warrior. Muur was famous for his sorcery, alchemy, and force-using tactic.
XoXaan was both a battlefield commander and skilled healer, leading their elite troops into battle.
Remulus Dreypa was their admiral, and another warrior/sorcerer.
Finally, Sorzus Syn was the greatest alchemist and crafter among them, and she takes primary credit for the creation of sith Leviathans (though Muur may have played a role). Possible creator of the Sith code.
Those were the five originals of note, and every glimpse of every one of them that we've seen suggests they were badass as heck.
And they considered each other rivals and were known to plot against each other, or at least the four non-Ajuntas certainly were, we can extrapolate that they must've all be pretty close in power in their own ways.
Sorzus's section of Book of the Sith was the best part of it. Lost Tribe of the Sith: Spiral was a pretty cool comic, and Vector managed to sell Muur as a huge cross-era threat.
The guy who wrote Revan was the same guy who created the character to begin with. Doling out bits and pieces is fine, but some characters never ever ever need their own central story.
Contrary to popular belief, I think giving Palpatine his own book was a bad idea in the long run.
