I am here for the starwars so for me it's SWTOR
That being said, I tried WoW a few times and it offered a lot of cool stuff and seemed like a fun game, it's a bit too cartoonish for me and the character models for humans are pretty ugly, but it's based off the warcraft games and that was the way warcraft looked.
I am not an elves and fairies type of guy, but if I did not care either way and was just looking at gameplay alone then maybe I would go with WoW.
They're changing the models in the next expansion actually.
Quite the overhaul.
Especially for the Humans.
