I made the decision to dig deeper into this game despite the negativity of the comments over there. I just wanted some input. I didn't expect complete objectivity, although a couple guys said encouraging things about AH which is basically what I wanted to hear, and not from here.
Trying to put this the most polite way possible... but when you down-talk something you obviously know little about (not trying to be rude/negative, but you are very unfamiliar with the way things work in Aces High, obviously), and then post a link to the forum you made it in... you've got to expect that kind of response.
Most of the problems you encountered are simply because you don't know what you're doing... again, not trying to be rude, but the 'I can't avoid a P51 in a Zeke' and 'I can't snap stall a 110C' make this very obvious.
So, some advice...
First and fore most, turn off the stall limiter... these are nice training wheels for newbies who have never flown a sim before, but as you've flown in Il2 for a while it won't help you much. The stall limiter, as a trade-off for making aircraft insanely easy to fly,
severely limits performance, as well as, I imagine, making the aircraft feel similar.
Also, many of the aircraft have been updated from their old AH1 graphics models, but some still haven't... the A6M, Hurricane, 110, etc. are far from equal to the F4U, P39, La7, etc. that have been recently updated. Also, you can shift your head view up VERY far in the Bf.110, letting you get very nice deflection shots due to it's over-the-nose visibility.
Hope I was of some help...
