Before you read this, keep in mind I play realistic mode or sim mode for tanks, and almost only realistic mode for planes. I did this in the general discussion forum for War Thunder. There is a night/day difference between my score as a fighter pilot and that as a bomber pilot. Sure, while flying a bomber, I can occasionally have a really nice mission, but if I play 10 fighter missions, then 10 bomber missions, all at the same BR, the fighter scores win hands-down.
Bomber pilots in this game are gimped to the point they are flying targets. The higher the BR, the more vulnerable the bomber. The B57A seems like an exception to that, except B57A's have to land to get more bombs, and the enemy is all-too-happy to shoot them on the ground. (and no fighters seem inclined to fly CAP at the home base.
