Nonsense. There is a juvenile prejudice against Spitfires but there is no actual reason to avoid them. It's an excellent choice for a new player.
Hell, I already said it my opinion. For a newbie, it is a good choice, I won't argue that. But the way I learned AH, by flying 109s till I finally got it right (or at least to the point where I can get kills), felt much more satisfying. When I decided to give a Spit a whirl, I felt like it was too easy.
Like I said, thats my opinion and how i learned AH.
