I just made the switch from WB to AH myself. I was a 2.77 pilot though...
Liked AH graphics, outstanding framerates (I am getting 20 fps in dogfights on a 64MB Celeron 233!)
Plane selection overall about the same, but some new things to try (LA-5, .202 etc)
I find the Main more chaotic than WBs; am finding it hard to fit in
I die a lot more here
I hate the fuel mods in the main; hard to get to 30k and stay awhile

I could never go back though ...
As a squad...
- You can fly squad night and not worry about upsetting the balance in the arena
- with the ground and naval game, you can come up with more varied missions (I love strafing PT boats)
- nice mission planner to help the squad
- built in voice really works well
Give it a try, I like the way HTC is constantly evolving it
