Darth Vader was Galen Marek's master, and Luke Skywlker beat Vader. So I suspect Luke would outclass Starkiller.
Anikin
Darth Plagueis
yes starkiller proved stronger then Darth Vader in both the force unleashed 1 and force unleashed 2.
I think Preston would win because Luke is a wimp.
Luke Skywalker :)
Luke Skywalker.
The cast of Resolute - 2011 includes: Marc Trottier as Luke Starkiller
Luke Skywalker because he is a Jedi.
While Starkiller was undoubtedly an impressive fighter, Revan was a highly skilled Jedi Knight, and a very powerful Sith Lord. The greatest of the era. As awesome as Starkiller is, I'm afraid he'd be no match whatsoever to Darth Revan.
Colossus
Darth Vader has beaten him in Empire Strikes back and it would take him 6 minutes to beat him since Luke sees how the force works. But it eventually got to the part where Vader cut his hand off. Darth Vader would win.
The original name was Anakin Starkiller. Actually that was going to be the name of Anakin Skywalker. Luke's would've been Luke Starkiller. First answer was right. Lucas gave the character the name Anakin Starkiller and later decided on Luke while giving his father the name Anakin.
