I remember in his biography, Erich Hartman preferred the ME-109 to the better performing FW-190. After reading this, I wonder if the 190 really was the better performer.
I do know that late in the war the Germans had developed a really powerful engine for the BF-109. I think something like 2000 HP which should have been a real terror in such a small plane.
Gunther Rall felt the same way. Matter of trust I guess. I heard the 190 had some problems in a dive.
That was the reaction of The Israelis to the Avia-S-199 (Czech Bf109)
Bigger engine, heavier moving machinery, more torque effect, add narrow undercarriage=beast
