The fact that WoW has been out for around 4 years and still has server issues, extended maintenance, class balance issues, class's that petition they'll quit the game, and numerous lag/other server problems just shows that its not much better. AoC just came out and has a lot of potential in the future to be a really great game. Its not cartoony like WoW is, fatalities are really fun and awesome and the zones are pretty sweet. I'm getting a new computer soon my old one was really outdated so I'll be able to enjoy the game even more soon

Gold can be tough to get but when I played WoW I had over 20,000g and no problems which is pretty much same with this game just gotta know how good ways to make it. PvP I haven't done much of because of my lack of computer power but they do have plans to release PvP based gear and titles.
Personally I haven't encountered any bugs and I am level 30 so far. I find leveling pretty quick, questing is really easy and gives great XP. I actually really like the map feature, it shows the whereabouts for each quest you have so you can easily group your quests and go from quest to quest.
I recommend trying it out its a lot of fun.
