Bf-109 G-14 like the spixteen?!? Er, ive never felt the similarities...
Personally, on the deck, I take the Bf-109 G-14, but as soon as you start fighting at 12,000 or above, I take the Bf-109 G-6. I actually find the Bf-109 G-6 to be the most maneuverable of them all, to the point where the only reason I ever take the Bf-109 G-14 at all is that mk 108.
