Boba and Jango Fett. The only two normal motha-blam!-ers out there that took on Jedi one on one and nearly won. Not to mention, Jango killed a Sith himself, which is why Count Dooku choose him to be the genetic donor for the "Clone Army", whose true purpose in a certain way was to help eradicate the Jedi Order as seen in episode 3. Anyone who played Star Wars Bounty Hunter knows this haha.
