Kurfie had a list:
"IMHO, counterparts with good balance :
1939
Spit I, 2-pitch, 87 octane vs. Bf 109E-3
1940
Spit I, CS, 100 octane vs. Bf 109E-4/N or E-7/N
1941
Spit Vb, +12lbs, vs. 109F-2 MG151/15
1942
Spit Vc, +16lbs vs. 109F-4 MG 151/20 at 1.42ata
Spit IXF Merlin 61/+15, vs. 109G-2
Perhaps G-2 would suffice instead of F-4/1.42, as they are similiar in performance and 109G was more typical
1943
Spit VIIILF, +18, vs. Bf 109G-6 at 1.42ata, opt. glass head armor
1944/45
Spit IX/XVI at +25 vs Bf 109G-14 with MW50. optional MK 108
Spit XIV +18 vs. G-10/1.8ata with MG 151/20. Also stands for G-6/AS and G-14/AS.
Spit XIV +21 vs. K-4 at 1.98ata and MK 108
This would bring a very balanced Spit vs. Messer setup."
Quite good IMHO
One edit would be a 1943 Spit IX LF with the merlin 66 or 70 +25, - but again, they are very similar to the VIII.
Then it is also the question of clipping or not. A hangar option?
