A long and complicated series of quests about poop? 
I don’t really know where EQ2 stands at the moment. Do they have achievements yet? They have player housing and that’s something I do miss a lot in WoW.
WoW has guns and explosives and hand grenades. I like it but I know some people prefer a more purist pre-technological approach.

I seem to recall WoW having more and better holidays - not just real world but Azeroth centric stuff like Brewfest and Summer Fire Festival. But that’s been an evolving thing.
The quests in Lich King seem to be moving toward a more heavily scripted story based stuff and less “bring ten bear asses”. But that’s sort of relative. Don’t know where EQ2 stands on that.
Oh, does EQ2 have quests where you torture people? Lich King has a couple. The only one I’ve done has been the Death Knight one which was oogy but narratively relevant. It’s a coin flip whether this counts as a pro or con.
Wow doesn’t always take itself as seriously. Again, coin flip - people seem to either like or not. This is part of what people have said about liking the graphics even though they’re sort of cartoony (I agree with this, and also about WoW’s superior animation, fwiw) and how the graphics really work with the silliness.
Overall though, Blizzard games are known less for doing something new and more for doing it better. They tend to build and polish and streamline into a game that’s highly playable and easily accessible. They have a kind of genius for it. That’s what Cisco meant about Blizzard loving gamers, I think. SoE is not so high on ease of use in their games and it showed in EQ2 at least while I was there.

Still, the main point to the game for most people is to do the same kill-loot-sell-buybetterstuff-repeat cycle that is the fundamental basis for both games.
