Bombers suck, torpedo bomber suck even more, I mean, they are LOTS of fun to fly around, but they don't earn shit, bombs are too weak, and exp/cred gain is piss poor. That kind of ruins the whole experience.
But I love my fighter-bombers, those are epic.
Which P-47 should I grab? Which plane should I replace? The F4u-1a or the F6F-3? Maybe the TBF too but it is my dedicated bomber right now until level 10 when I start using my BTD-1
Can you actually choose? I'm pretty sure you gave to get the -25 before you can buy -28. There's no difference between them really, just different paint job. About replacing, Your preference really, F4A is a slightly better fighter, but F6F is a "mini-P47" so you lose that ability to destroy ground targets.
