Master Crimzon
Baby Killer
I can't stand 'em. Here's the deal:
Sabers- The prequel guys, obviously. Do I really need to explain why? Well... Obi-Wan, the ultimate master of Soresu, Mace Windu, the inventor of the 'deadliest' form, capable of attacking so fast multiple arms are visible, and Anakin, the 'strongest and fastest Jedi' of his generation, a guy who grows stronger as a fight progresses thanks to his virtually unlimited force power. The KotOR guys lack any sort of known skill with a saber. They definetly die.
Force- Triumvirate, with ridiculous ease. The only real 'force' factor on the prequel's team is Mace, and even Mace's impressive displays of the force can't match Nihilus' raw power and sheer ability with the force, and Traya's drain and arsenal of powerful techniques.
All-Out- Triumvirate wins. I do, however, see Sion dying, as he is clearly the least powerful of the triumvirate and seems to focus primarily on lightsaber combat. Any one of the Jedi can simply disable him or decapacitate him. However, even if that happens, the team gets eaten.
