I see virtually all the responses have been from fighter pilots, but I only fly fighters in moments of utter bish desperation and wanted to put in a plug for my favorite plane, the Ki67. Excellent speed and climb rate for a buff, formidable guns, and it takes a lot more damage than many think it ought to.
My fav plane to fight? The Me262. It's a big target and as long as I have a little E I can maneuver to get a pretty good shot at it as it swooshes in for the kill.
