Based on K/D ratios and proven combat performance (as opposed to speculation) I think the list would be a mite different... the 109, F6F and F4U would prolly pop up somewhere on the list, the pony would drop to the bottom.
As a moot point it would be interesting to see how a pair of F-22's would fare against a pair of Eurofruits or even better; a pair of Froggy operated Ralphies. Then just to validate the ralphie results, give it a try with non-stinky competent euro pilots in it.
Oh, well; all idle speculation till the next war...
