Later FW 190 like the Dora-9 and Ta152H all have liquid cool engines optimised for higher altitude fights. They were more of an interceptor than a dogfighter,
The german 30mm 108 guns led to the French DEFA and British ADEN, eventually to the powerful BK27 27mm gun. Powerful weapons those.
Russian fighters like the La-7 and Yak-9 were excellent low altitude fighters and were quite tough.
