If we're critically thinking about this then it doesnt make sense why caps cant use snacs. What you dont have enough room on board for snac mounts? Bottom line is snac is OP.
As far as balancing bombers go, they are a little heavier with usually less armor but very big mains guns and very light and fast other guns (such as the single person controlled guns).
The end result is in no way does the bomber (top) compare to the fighter (bottom) for agility or speed.
