Spitfires are less dweeby than 109's.
I find myself more successful in 109's than in Spits. Simply because 109's 9/10 can disengage from a fight, extend, gain alt and rejoin the fight. 109 G14's are the best IMHO, turn tighter than a K4, and are still quick enough to cause most aircraft a headache.
Spitfires accelerate and turn much better than almost everything, however as stated above. It is ALWAYS on the defensive against 51's, 109's, 190's. Its only capability is to dodge and hope the pilot is dumb enough to maneuver. Zekes and Hurri's out turn and out gun them as well.
