Well the P-47's are hard to use where the spits fly, the P-47 I find is good in two roles, either low alt escorted attack, or as a very high alt fighter, at 20K and above is where I find the P-47, the N most of all, damn near being a god among the AH lineup. Same goes for the P-51D (The B is alright at alt).
The spit 8 and 16 seem to be more of a low alt only type of fighter, I know the 16 is for sure, but the 8 I'm not totally sure about thats just what I'm getting from these forms. The mk8 I don't think should be perked from what I've noticed flying, but the 16 is a low alt beast without much of a drawback that I've seen yet...
Lots of people talk about the same thing with the Ki-84, but it's main drawback is speed, it doesn't handle it well at all and you can easly use that to your advantage. The Mk8 and 9 seem to have only slight disadvantages in speed to turn if any to most planes and if not it's got one way better then the other. The Mk16 seems just as good as a mk14 but for low alt use, the lower alt engine, clipped wings and new rudder it's freaky at low alt! It's turn rate seems to be lacking slightly from the clipped wings but the powerful engine seems to be able to keep it moving even well hanging on a stall!
I think the Mk16 should be perked just the same as the Mk14, the Mk8 I'm don't know enough about but I find it to be a sweet looking ride (lol) and the rest seem just fine now that the Mk5 has been toned down, I've noticed the total lack of engine power.
I find the Seafire to be perfect! It has a good perfomance zone that I really like now and that tail hook looks freakin' awesome! lol
