What makes this video so entertaining is we can compare the armor differences between the two sub-classes of Jedi Knight, the Jedi Guardian and the Jedi Sentinel. You want to be a one-handed-force-wielding-tank-and-spank-bad-ass? The Jedi Guardian armors will have more of a sci-fi/knight of the round table look to it. If you want to be a dual-wielding-damage-dealing-whirlwind-death-machine, well your Jedi Sentinel armor gives you a more agile and dexterous look to it. One thing the two armor classes do have in common is they both look pretty awesome.
Yes I know it's not all about how you look, but when you're out in Hoth riding your Taun Taun into battle, it doesn't hurt to look a little snazzy while doing it.
