Well, the Ju 88 is very maneuverable for a bomber, but the Boston III flies circles around it with complete ease. 2bighorn and I spent an evening dueling with the two, and the Boston was so superior it wasn't ever a real contest.
As to F3 view.... If your fighters are being shot down by maneuvering bombers, it's easy to blame F3 view. However, the reality is that you truly stink. Running up a big kill total in the A-20G, for example, is a result of beating players who could suck a baseball through a garden hose. The fact is that the A-20G is inferior to virtually every fighter. It is good enough, however, that a skilled pilot will beat the average player without much stress. Much of the A-20's perceived advantage is that few players expect it to maneuver fight them. It holds E well, has good flaps and a gentle stall. Combine that with 6 guns packed into the nose and you have an aircraft that is very lethal should someone find themselves in front of one.
Look at the SBD and TBM. Two .50 cal MGs is adequate if you can saddle up briefly. Both will out-turn the bulk of the fighter set. A TBM has the same turn radius as a Hurricane. The SBD is even better. However, they are little more than helpless in a vertical fight. Yet, the average player will not think in three dimensions, but try to turn with them and pay the price.
F3 view allows a pilot to see what he's blind to. It simulates having other crew members to spot and report the enemy. It improves SA.
It does not improve your flying skills. It does not improve your aim. Sucky pilots using F3 are still sucky pilots who happen to see better behind them. That's all, nothing more.
So, to repeat the key point... If you are having trouble with maneuvering bombers, the problem is you, not the bomber's F3 view.
