So the top 10 consists solely of books about allied planes? Sounds like a true non-biased approach to subject.

Okay- name me one book for axis aircraft that even approaches America's Hundred Thousand, or Bodie's Thunderbolt book.
Just one.
I'll make it easy on you- there aren't any- at least, none that I know of. Data for axis fighters is generally much harder to get a hold of. Indeed, the best resource we have for information on 109's and 190's is from the flights/fights that Hannah had.
Not biased at all, it's simply based on what is available. You may have a ton of information (both bad and good i.e. Jane's and Bodie) for the allied fighters, but the axis fighters' data is plauged by rarity, and even then the majority of it all is anecdotal. Russian a/c data is, shall we say.....skewed a bit. But don't let Oleg hear that.

Japanese fighters are generally well documented simply because that's the way the imperial war machine rolled. That and we got a zero basically undamaged, tested the hell out of it, and made a plane to beat it- helloooo hellkitty!
