yup. i still play both, but if i should choose i'd certainly pick AW over EU.
i'm not a first-day noob in either worlds (67agi & 3,8k evade in EU; rifle 28 in AW) - unlike some ppl who never got further than the quarantine zone and already imagine they know what AW is..
so, why AW?
1. graphics are slightly better than EU's, see for yourself:
link to the slideshow
ok, external slideshows not allowed..

anyway, if u write

instead of the "%21%21%21%21%21%21%21%21%21%21%21" u can see it

loaded the images
to the gallery here also.
the overall style of AW is more realistic, more, umm.. let's say - clean, even harsh. EU is in places a bit too gaysh and disneyland-like for my taste
AW is post-apocalyptic, with a touch of japanese/chinese aestetics. in a word - something for the snoobs
all that said - avatars in AW are pure crap! there was a plan to implement real avatars, but it's postponed atm.
2. more excitement - almost all the world is a
PvP zone. meaning u can be killed by other players anytime. actual killing is quite rare but still, it gives the whole world a different feeling
there are negative sides to it also - as most ppl come from EU, they suppose in general everything should work as in EU..
when killed in
PvP 
some of them lose their temper and start whining - ingame and on the forum..
3. post-apocalyptic setting. no fancy teleport chips for example. if u are too weak to go from point A to point B, u have no way to go there (
without help)
again, EU people feel it's a Human Rights Violation

but soon realize it's much more realistic this way
4. crafting is better than in EU
5. mobs AI is slightly better than in EU, more fun!
6. not a casino
my 2 cents, but, well,
