icejaff,
The Spitfire is indeed a great airplane. An aircraft capable of matching just about any plane in the game in a 1v1 if flown well. However, it is their reputation in AH that is questionable. Majority of newer players and/or people who don't know how to fight tend to fly it. Because you are new, I recommend taking some time by flying the various Spitfire models first so you can get a feel for the fights. Once you're comfortable, you can start flying planes like the F4U, 109, 190, P51s, and the rest of the planeset.
If you really really want to challenge yourself, fly the P47. From my experience, the P47 is quite possibly one of the most, if not THE most, challenging aircraft to master in game (followed closely by with the P38). It is outclassed in almost all categories except for high speed handling, firepower, and ruggedness.
So pick a plane, fly it for a tour or two, then try something else!
