From a US perspective, either a P51D, P40 early on, and/or F4U. Fighter missions, not jabo, if I could choose. I'd fly the P47 too but not for jabo.
German plane would be the 109s for sure. Preferably probably the F model, and then g14 with goodies. ..
British- Spitfire for sure and then tempest later
Japanese - probably the a6m early and the Ki84.
Russian - la5/La7 probably
