Dragon Age starts to have ridiculous long loading screens at some points, I was amazed with how short D2 were (a lot like 2 worlds actually), thou it comes at a price of a lot of stuttering, and it does need to load quite often... but I prefer D2 loadings over Dragon Age ones by far.
Although I really loved dragon age, I enjoyed D2 much more, but that doesn't mean its not a very good game. Even story wise I liked D2 more then DA mostly cuz it didn't have stupid stories about harsh dwarf politics and elves who lives in forests and hates human and the likes, I got sick of those stupid uninteresting lore that so many games came up with lately and still think its original (it wasn't done badly, I just got tired of it). Also D2 delivers its background lore with short books (some with nice humor) while DA thou boring and very long and pointless codex's or something.
However, I really appreciate Dragon Age for making me enjoy and play a game of which genre I mostly hate (I can't stand neverwinter nights, I think all copies of it should be burned). To tell the truth thou, what I liked most about dragon age is how realistic the moving\ running feels, stupid as it may sound, I simply loved running there... (not that it isn't fun in D2 ofc, your jump is epic!)
I LOVE BOTH OF THEM, but I enjoy D2 more for many reasons. I also prefer Risen over Dragon Age, but I haven't finished Risen (which I really like so far) so I can't compare it to D2, and that will make my comment to long if ill write about it
