Assault Rifle: Harrier. Incredible damage output, especially with an extended magazine. Really, the former is pretty much required, but even with one mod slot spoken for it's better across the board than most rifles.

Pistol: Paladin. Essentially a high-powered sniper rifle, minus a built-in scope and half the weight. Honorable mention to the Arc Pistol.

Shotgun: Piranha. The optimal vanguard shotgun, with high DPS, a large clip, and surprisingly low weight. Also good as a secondary weapon for soldiers who like to use adrenaline rush/marksman more than twice per minute. (I can't comment on the Venom.)

SMG: Hurricane, for obvious reasons.

Sniper Rifle: Valiant. Excellent DPS, and versatility that's sorely lacking in the other endgame snipers.
