It also depends a lot on the type of fight you prefer. I myself like to do inverted loops and fight in the vertical dimension, instead of going in a horizontal turn-style fight (Where Spits and Hurricanes rule) and the BF109 is a great plane for that, because of the powerful engine and high manouverability near the stall point at the top of the loop. If you are silly enough to accept another stule of fight against a slower but more maneuverable plane, however, you might get screwed fast.
