[Star Wars] Top Three Darth masters in history?

If you were going to give the Washington, Lincoln, Roosevelt (or Charlemagne, William the Conqueror, Napoleon) of the Darth masters who would they be?

Let's do Jedi masters while were here.

I am only a movie watcher so when I popped on the wiki and saw a near endless list of Darth masters I got intrigued and want to read about them. Got too many books in my to-read list to start on the books but I want to poke around on the wiki and am looking for some good interesting places to start. So feel free to recommend some other wiki stuff to read in general...

What about Darth Nihilus (from KOTOR 2)?  Although the final confrontation with him in KOTOR 2 is not particularly noteworthy, the fact that he was able to absorb the life force of the entire biosphere of planets using the dark side of the force definitely stands out in terms of raw power.
