Probably hyperbole, but I've been with only asians so long I don't even like how white chicks look for the most part anymore. (There are gorgeous white women obviously, but in general I prefer how asians look.) White chicks also age like shit.
I guess I'd say it's less about race than it is about culture - I really like the small subset of culture you get from asians that have lived in the US less than a generation. If you could put white chicks in the same situation they'd probably turn out similarly, it's not really racial.
As far as avoiding princesses, sure. I'm sure there are non-princess white girls. But there are other cultural factors too; white girls don't tend to upkeep their appearance (weight) the way asians do. You should hear the asian girls mercilessly hammering each other on their weight when they all weigh under 105lbs. My wife will have a fit if she gains 2lbs. She weighs the same now as she did when she was 19. And I know, because I was fucking her then too.
I know the fat apologists will be all "I don't want a chick who is neurotic about her weight! What about having fun and enjoying life!" ... ok, enjoy waking up next to a fatty then.
