If you flew in the AW FR arenas at all,you'll do fine here. Blackouts are more progressive(instead of AW's nearly instant blackout),and departure into a spin has a better feel...you can ride the stall better here IMHO.
Are you saying AH is more realistic?
After fly at AW FR for 3 years and 3 years more at RR arenas. I feel AH is between both. It's more difficult that RR arenas and more easy that FR arenas.
Of course, better graphics, better ammo choices, convergence exist here, worst fuel choices (i want to put my plane 99% fuel what is the problem too difficult?), better damage model (worst that Il-2), worst community that at AW FR (90% people don't respect 1 poor low guy between 2 or more enemies for exemple, result quake arena with wings), if you employ german planes at AW you will have a problem here, some planes breaks aerodinamic's law (la7,nikis,spits and near all buffs). And you will love be killed for a ground vehicle or buff gunner about 2k distance when only thing you could do is look him, better patches that AW, more advanced planes that fly (WHERE IS KI84?

)
Personal conclusion: a global better game that AW with some mistakes, for me that mistakes are easy to avoid but seems some AH veterans begin to emigrate IL-2 because thay hate Quake games and there is where AH is going.
