Very interesting post, full of historical information about real FW and Spits.
but
in this game all FW series are TERRIBLE compared to spitfires.
Maybe FW can be faster or roll faster than a spit but an overall sums of all his aerial combat performance place it very under what a spitfire can achieve. Talking about turning, spitfire outturn FW very very easily.
So be carefull when flying against those!
My final answer to your question is that on PS3, Spitfires are better than FW (and also bf190) series in pure 1 vs 1 aerial combat.
