during BOB both planes had almost the same specs
EXCEPT that the Spit was a little faster than the me109 and the me109 could get higher than the Spit
Accordind from pilots of BOB they said that the main feature of the spit by far was that could make tighter turns
the best escape maneuver from Luftawwe pilots was to stick forward and dive while the Spit had to roll over to dive and follow him
so this little things makes this planes better than the other ones
Personnal i like to fly the me109
