My only real issue with the 16 is really that it is pretty good at... well... everything...
It's one of those aircraft that when it gets behind you, you really have no idea what to do. Should I dive? No, not unless we are way up in the sky, it can dive pretty well for a period of time, but then I'll be low on E and he'll just climb back up... waiting for me... Should I climb? No, it can out-climb me off WEP, and catch me when on it. Should I turn? No, it turns tighter and rolls faster. Should I chop my throttle and force overshoot? No, it slows down very fast, not to mention accelerates quickly as well. Plus with those cannons if I give them even a split second of a gun solution, a wing comes of. I could try to just out run it! Ah, wait, no... those Hispanos will get me before I even have a chance to get out of his speed range.
Ah screw it, I'm gonna bail.

In all seriousness, it is truly a challenging aircraft to encounter. It always steams me a bit when I see a "vet" pilot in it since it seems so... challenge-less... I've even had moments where I'm cruising 3k-5k above a Spit 16 at 300mph watching him to see what his next move is, just to stare at amazement as he pulls straight up, comes co-alt with me, and accelerates to 300mph all in enough time to gain a gun solution on me with those vicious hispanos.
I just can't help but feel that a plane that really has no real disadvantage shouldn't be perked and that it isn't unbalancing in some way. However, I do feel that it's a good idea to have aircraft for beginners like this one. Either way, I really don't think just looking at kill/death ratios or usage percentages is going to give us an answer.
My $0.02.
