I think each release of AH has seen a very popular plane. I can remember everyone flying the P38, the 190a5, Yak, Zeke, when they first came out or when they were something special. I still see a lot of 205s, 109s, La5s, P51s flying about and the only planes I don't see that often are the 202 and buffs in general!
No doubt with 1.05 it will be the Hellcat or PT Boats or whatever... I've always flown Spitfire's so I'll continue to whether it's uber or not.
