I personally do not like the later plane sets 44' and 45' on WoP for the same reason, when you're low you're food for the spitfire, and when you're high there's the P47 and P51 fighting for every single screw on your plane.
That doesn't stop me from flying bomber sorties though, often the Arado Blitz bomber is available and you can perform some serious bombing raids with that magnificent plane
