I think (but I could be wrong) I like all of them!!!
I really do try and fly every single plane. IMHO you gotta know what each plane will do against every other plane.
That way when you see an N E ME plane you automatically know how you wanna fight him. Then you just fly to your planes strengths against his planes weaknesses.
I've found by flying every plane I can get a quicker handle on the characteristics and differences than parking in one plane for a year. When I've figured out the ones I really enjoy flying in then I tend to use them a lil more often. But, you'll still see me in a different plane from time to time. Heck, I think I even flew a Spit last night on a sortie.
One last thing to note....whenever I see an enemy plane I go after him so I guess it doesn't really matter what it is I look shooting at em all, too! I may not win every fight but it wasn't for a lack of trying

And while I don't record every fight anymore I do look for what works and what doesn't at every encounter.
