I agree with ghosth but would say A5 rather than A8. Obviously depends which arena you're talking about but for LW Yak3, C205 & 190a5 would be my choice. Middle range ENY but not US would probably be your aim. Plenty of good middle range US planes but relatively well used because of subscriber profile.
Yak3 imho is best all round fighter in AH but lacks huge popularity because of relatively low ammo count. But if u don't spray & pray, get in close, the 20mm & x2 12.7mm are axial & closely grouped & will punch a hole in anything with a short burst. 3 kills ps is not unusual, even bombers. It's fast, nimble & great visibility.
C205 is good all rounder but doesn't excel in any one area apart from cracking climb rate. Dives well, hits hard & loads of ammo.
190a5 also not seen too often but one of my favourites. Reputation marred by poor turn radius (like all 190s), but has roll rate which is 2nd to none and often more than compensates for poor turn with experience. Fast roll is maintained at speeds that have many planes creaking with stress. Feels more nimble than other 190s ( I don't take extra 20mms) & can often be landed with a few kills and ammo to spare.
