It would be nice to have every variant of every aircraft
If we limit the discussion to the Spit XIV, 109K, and P-51H per above replies: the Spit is already done, the differences between the G10 and the K are negligible (effectively already in the game), that leaves the P-51H.
However, there are plenty of aircraft more common that actually flew combat. Most notably, the late P-47 variants.
But I could care less about rare perk planes.
Early P-38s, P-40, P-61, F2A, F4F, Frank, Oscar, Tojo, Jack, MiG-3, etc. all rank higher on my list than the fabled P-51H. Of course, being a pony fan, I would fly it anyway. However, I am a big F4U fan and I primarily fly the F4U-1 and the F4U-1D. I have almost no stick time in the -4, and normally only resorted to the -1C when doing base attacks or tired of Typhoons/Tempests in HtH.
