I-153 M64:
Decent speed, very good agility and very nice rapid machine guns to kill pilots
BF109F4:
Very fast, good armament, very stable in diving.
SpitFireVIII:
Fast, turns really fast and is very stable good armament
FW190A5:
Good speed, not very agile thought but I mainly use it to take down bombers as the armament on the FW190 is very destructive.
BF110:
Good speed, not very agile, the acceleration speed is not really satisfying but once in the air on good cruising speed its terror for slow moving targets like IL2's and medium bombers. also a very good groundpounder. also a very stable.
B25:
Good speed, good defences by MG's on most angles
can carry a very good load out. and she can take a pounding and still make it back to base
JU88:
Strong engines, speed is good. Like that you can use it as a dive bomber as well. the defences are something to worry about when you fly without escorts. the load out it can carry is very good.
thats my list
