Ghosth, top 10 based on numbers of kills or on kill ratio? The reason I ask is that you would get considerably different results from either of these measures.
Perking based on total number of kills would be roughly the same a perking based on usage. By this standard, the 262 would not (probably) not be perked even if free. (Anecdotal evidence: During my Warbirds days, the 262 was not flown that much even when available. Poor shots had a hard time getting kills in it, good shots quickly became bored with it.)
Perking based on the kill ration would end up with the Ki-61 (which tends to have about a 1.4:1 ratio) perked in the top ten. (Based on the monthly full tour stats posting.)
So which method would you use to work out the top 10? Or is there another method that would give consistent results?
For conversation, here are the top 10 "monsters" for last tour using these two methods:
