I was suprised the mossies not anywhere on the list....
Looking at just this months raw numbers a couple of things really suprised me.....
1) Looking at a few of the well known rides the "leading" model isnt the "best" one...
Spit VIII 0.9442 vs Spit IX 1.1243 [spit XVI 1.0959]
P-38L 0.7951 vs P-38J 1.4710
P-47N 0.7902 vs P-47D25 1.531
190D-9 1.3574 vs 190A-5 1.3915
I left the 109 off since it's not clear cut with all but the E holding up well and even the E doing much better then the spitI or P-40B etc...as a "cult" ride:D the 109 attracts a "better" overall class of pilots I think...{actually within the scope of the airwar as presented in AH its a very good plane} with the F being a greatly under appreciated killer...
Here are the random things that really stood out to me....
The 190A-5 has a significantly better k/d ratio then EVERY spitfire (so does the A-20:aok )
The 109K, 152 and Tiffie (in that order) are the top 3 non perk k/d ratio birds...
The 190A-5 has better numbers then the hurricane and La-7 as well....
So I draw the following conclusions based on the raw data....
1st and formost as I always have said the A-20 is as good as any fighter:aok

since it beats all the spitties the hurricane and the la-7.
More seriously however good pilots have favorite rides...
The F4U-1a, P-47-D25, 190A-5 and P-38J & SpitIX clearly stand out. your statistically more likely to be facing "baron von uber" then "the bonnie noob" when you meet one.
Also the A-20 appears to attract a better class of pilots then the Mossie or 110's since the numbers are so skewed [A-20 1.4, 110G 0.64, Mossie ~1.0]
Obviously to some degree the lower numbers on some planes reflect the Jabo lemming role to a degree while planes with low use have numbers skewed as well [moot, ww etc in 152 this tour?]
Overall my biggest suprise is the mossie having such low numbers. Even with Jabo/gv hunting I'd expect it to have numbers on par or higher then the A-20 given its speed/firepower advantage....
*** at edit ***
I left the hogs out above for same reason as the 109's, only suprise was the poor numbers for the D and the fact that the C actually has better numbers then the -4
While I certainly cant disagree that the -4 hog is easily the best fighter in the game (prop or jet IMO) it isnt readily usable by even a "better" pilot IMO. The strengths are formidable but subtle since its as much in the combo of "slow speed" & power/acceleration" as raw speed or firepower. IMO most sticks fair worse in the -4 then in a tempest la-7 or other ride unless they fly the other hogs reasonably well....
