Lynx has a good point. Even if this is his subjective remark, I fully agree with his plane choice. I believe majority would agree with it too.
Look how many competitive fighters the US planeset has: 7 !!
All of them have abilities to be successfull in the arena, mainly speed and guns. As late war planes should.
And other countries ? 1, 2 or 3 maximum.
The rest are hopeless underdogs.
We can discuss competitive LW planes, since I flew them for a little while:
Me 109G-10 - great 1 on 1 plane, but lacks characteristics for many vs many type of fights. Also has serious problems at high speed. The plane has "target fixation" written all over it (you want me to elaborate more ? ).
Fw 190A-5 - mixed bird, good allrounder, but too slow sometimes. If faster, it would be very competitive, but now falls somewhere in the middle.
Fw 190A-8 - deathtrap for newbies, but very effective with experienced pilots. Still lacks few miles of speed. IMO, the best choice for a dedicated Luftwaffe type in AH.
Planes like 109F-4, Spit V, Mc 202, or Zero may have added numbers (or even a year, in case of Zero), but not the performance of late war planes. Those have been left out so far.
Why hasn't the P 40 or P 39 been modeled instead of P 47D ?
