Darth Sidious
We'll start things off with the most powerful Sith in the Star Wars universe. Darth Sidious has been a character in many storylines over the years, most notably in the Old Republic comic books.
Physically, Vader is stronger due to his cybernetics, and has greater endurance feats, and while I do believe Nihilus is more agile, I'm more than sure Vader can keep up. As duelists, Nihilus is a bit above average but not in Vader's level. So with all that said, I declare Darth Vader, the battered and broken victor.

A lightsaber could probably cut the Hulk but that's not the problem. The problem is that the Hulk can regenerate his body to an insane extent and now with knowledge of what the Saber can do he can change his tactics.
Darth Vectivus. He basically got all the power he wanted and then retired to live with his family and friends and died peacefully, none of the Sith backstabbing. Vergere is potentially another (although I'm still pissed at the retcon of her being Sith).
In canon it was Kirak Infil'a , Cere Junda, Obi-Wan and Lord Momin . All messed him up quite badly with Kirak winning round 1 but losing round 2 and Momin cutting off his arm. Obi-Wan actually beat Vader. In Legends it was Shaa Koon, An'ya Kuro, a clone of Maul and Galen Marek.
