Trowa kicks a**. Though I do find it hard to belive He's the guy in Heavy Arms.
I like Heavy arms. Highly impractical for fighting, since you're based on ammo limits, but I like red, and i like things going boom!
Wing and Wing Zero were just uber, and no matter how cool they were, they were just overboard in its design.
Deathsythe is cool, but only one weapon really gets annoying. (2 if you count head installed vulcan cannons)
Nataku was okay.. Sandrock blows though...
Deathscythe Hell is pretty 1337 tho... i mean, it's basically impervious to damage with the shield down, and can nearly be invisible... not much need for long-range weapons when you can sneak in and strike with a powerful melee weapon (with notably long range)
Nataku, as much as i hate to say it, is probably the best practical one.. a good balance between melee and long range (as Altron, not custom).
but anyway, yeah...star wars...
