They both fly different, for sure. The 109's have that funny Torque-characteristic that makes them harder to turn right than left(Or is it the other way around???) The E retention is great, though.
The 190's change alot over different mk's. the A5 is really a nimble little plane with the right fuel onboard. The A8, of course, is most likely the most heavily-armed single engine fighter in the game, but it's handling seems to suffer because of it. The Dora is a great plane, Similiar in many respects to the pony, performance-wise. And we can't forget the Ta-152. It's the king speed demon, although that is at a height that very few ever reach in this game, let alone fight there.
