I'm a lover, not a fighter. I like the Tiger Moth.
It's a serious toss up between the Hurri and the 109. Aiming is easier in the Hurricane because the sight isn't off set. I fly with Track IR and am still not used to that in the 109 and the LEAN to SIGHT function isn't too smooth - especially when you shoot past an enemy in a boom and zoom, and you still need to track him. The reversion back to regular view is clumsy and time consuming. Unless there's another function I'm not aware of the LEAN to SIGHT is useless for me.
Barring that I like everything else about the 109. I have gotten better at turn and burn tactics with the Hurricane. I always BnZ with the Hurri in IL2. I seemed to lose my energy faster than needed if I TnB in one, but in CoD I've forced myself to try different tactics - especially because of the carb cut out on neg Gs.
I haven't spent much time in the Spit.
109 is my pick.
