There IS variety in high-speed b'n'z aircraft. These are the planes that run 355mph on the deck or better. 51s, D9s, Late 109s, Typhoons, F4Us P-47Ns to a lesser extent...you are liable to run into all of them them on every sortie. History Channel mentality skews this list abit to the 51 of course, but all these models have their strong and weak points inside the b'n'z niche.
There is also some variety in sure-nough, no doubt about it t'n'b aircraft. Any fight low and slow enough for them to be appropriate, you are liable to see A6Ms, HurriIICs, FM2s, Seafires, and the split-personality Corsair will make an appearance again, having dropped flaps and begun to make use of its tiny turn radius. You'll see a SpitV now and again.
The real problem comes in for planes of only moderate maneuverability and only moderate speed(320-360mph OTD), planes that nonetheless could potentially out-run and/or outclimb the Hurris, Zekes, and FM2s etc, and out-turn the Ponies and Doras b'n'z'ing them. For instance, the F6F, P38, P-39s, P-40s, P47Ds, 109G2, 109G6, 190As, Yak-9T, Ki-61, Ki-84, C205, and, oddly enough, the SpitIX. (I'm thinking of deliberate a2a use here, not the lemming-style bomb truck use the Hellcat, Lightning, and Thunderbolt see commonly.)
But unfortunately for these aircraft, the SpitXVI is basically superior as a fighter at typical MA alts, and very common (as we can expect such an excellent a2a fighter to be) Why fly any of the above listed middle-class planes when you can have something that has a better turn rate, and usually turn radius, a nicer gun package, much better E-building properties, rolls alot better, and doesn't have much in the way of quirky dive or handling traits, AND your chief opposition will be said wonderful machine?
