It's really not debatable.
Galen Marek, before his Mega-class empowerment, would also go on to curbstomp Kazdan Paratus, a Jedi so powerful that he was able to singlehandedly obliterate "entire legions of Confederacy droids" and had such a deep understanding of the Force that he was able to summon and create a massive droid army empowered only by the Force.
He's badass.
And so is Kota.
I R NOT!
Seriously, though, Paratus was capable of singlehandedly tooling "legions of Confederacy droids," building a replica of the Jedi Temple out of junk, and constructing a massive army of droids "well equipped to battle Sith" (one version of which is capable of creating a negative feedback field and drain the Force from its targets), and empowering them only through the Force.
Bad. Ass.
