Perk farmers

[Letalis]

Guess I'll throw my $.02 in.  My ranking below is based on personal impressions and not limited to the 30+ ENY range but simply overall perk farming efficiency which includes A-G ability. 

1. 109G2 for reasons already stated.  I'd also add that the swing-role diversity of gondies+centerline bomb give it the edge over the F-4. 
2. P-47D11
3. 190A5
4. F4U1
5. P-47D25
6. 109F4
7. 109G6
8. P-47D40
9. Ki-84
10. Brew

P39/P40 don't even get close.  Yak series and P-38 series deserve honorable mention.

 For GV perk farming the jagdpanzer Hetzer 38 is tops for me. The 109F-4 and 109G-2 are planes I like. I don't recall what the Yak-3 is but I flew it in the DA and that is a pretty good plane. I may have to give it a try in the MA.
