I haven't tried the game out yet. In fact I'm picking it up in the next day. With that being said, with all the research I've been doing, I'm not fond of Sylvari. I usually like woodland races, but these have a weird look to them I don't care for. Same with the Charr. I'm sure playing them will be a bit different, rather than watching videos!
Norn by far. They're just big humans. Wow exciting. The males aren't as terrible, they're a bit different, but the women. I guess they didn't want to risk making "ugly" characters so they're literally larger humans.
