It allows for a lot of maneuverability without any extra strain on the pilot, as well. Rolls suddenly become pretty effortless, since most Rebel fighters have artificial gravity.

With the added bonus that a B-Wing on an attack run can roll to evade enemy fighters without having the target of the attack run effectively spinning wildly from their own viewpoint.

Exactly. I assume they can set the orientation somehow, and it allows them to maneuver more heavily and maintain their orientation at less stress than a conventional fighter, which would give them an advantage. Plus it's harder to hit a small frame that's in near-constant motion.

Also it gives them a larger area of effect with respect to weapons, like SilverWook said. It's actually a pretty amazing design the more I think about it.
