Asking what plane is needed most begs the question... where? In the MA?
Most of the planes I'm seeing listed here would be hanger queens in the MA - limited usage, mostly by enthusiasts, and probably would be meat for most of the LA-7, Niki, 1944-45 fighter flying club that we see most nights.
Not that I wouldn't try out a Gloster Gladiator, or Fiat CR42, but how long can I reasonably expect to survive in one? Sure, I'd love to be taking off B-25s from a CV and trying a Doolittle raid, but I don't have much hope of getting home in a sky full of LA-7s and Nikis, and I'll be carrying the same 2K bombload as an Avenger (another hanger queen).
Since that (IMHO) is the case, why not feed that hunger first and get some new action going in the MA. My list is the 4th Qtr '45 list, and I'd expect them all to be perked:
USA:
F7F Tigercat (would've seen service if the war hadn't ended)
F8F Bearcat (delivered into squadrons prior to wars end)
P-80A (delivered before wars end in Europe, and would be an interesting match against the Me-262).
B-29A (conventional bombs only, and good luck getting them to target if you are under 25K).
Edit: Add the P-51H for you Mustang enthusiasts - lighter, faster, stronger than your old D models, and plenty built by wars end...)
UK:
Gloster Meteor Mk.III (saw operational service folks, we just never got the jet battle with the 262 that everyone was anticipating).
Spitfire F.21 (lets just see what the ultimate development of the spitfire was like...)
Germany:
Do-335 Arrow (some were delivered before war's end, and I for one would like to see what it would've done against a horde of bombers...)
He-162 Volksjager (delivered in 45, with operational training and even a report of action before wars end)
Me-262A-2 (why not lets see if the 262 can be used as a fighter-bomber, and lets see about those fat R4M rockets vs bomber streams too...)
Japan:
Ki-100 (Plenty were used, and it is arguably the best japanese piston-engined fighter of the war).
Perk 'em all, and let God (and the carnage that is the MA) sort 'em out.
