Favorite if not the BEST!!!
Fighter: USA: P-47 Thunderbolt with it's heavy bomb load, rockets and 8x50cal. guns, but the Hurrican and Zero come a close second for their great looking lines. They always look like they are out turning you even when they are standing still.
Bomber: Once again goes to the USA. The B-17F which brought the heavy bomber to life. I also like the early HE-111 and JU-88 of Germany.
Night Fighter: No question the Misquito, or wait the ME-110, or wait the HE-219 they all look so cool.
Well those are my picks...
