The only thing I think WoW seems to do better is PvP, but you have to remember that WoW has been around for a decade, so they had a lot of time to 'get it right' regarding that area of gameplay. Still, some complain that it is stale because it has (mostly) remained the same for so long. The biggest hurdle FFXIV faces in PvP is the lag of abilities. The overall class balance is nice... they just need to figure out how to reduce the delay even more than they already did the first time. I hope they come out with more large-scale PvP activities, and more incentives to do them (queues are discouraging). I *DO* like that FFXIV has three separate PvP factions. It makes things interesting.

Anyway, what I LOVE about FFXIV compared to other MMOs... The story. It really drags me in. I'm not often a fan of "You are the one hero and must save the world" stories -- I prefer a more relatable scenario, but FFXIV seems to do this one well, because it incorporates the fact that there are other Warriors of Light. It is downright impressive that SE comes out with a new, unique, produced song for every primal (although I wish they'd get a little more creative with coil songs... the same default song for a year is getting pretty rough).

As far as other things... weekly caps and lockouts, etc. That is pretty standard across many MMOs, FFXIV and WoW included, so that's really not a point of reference. And finally, the FF community, to me, has always been more friendly and familial than WoW. I'm not saying there aren't mean FFXIV players or nice WoW players, but my experience has been the way it is, and I suppose I'm a little biased because of my 'rose tinted glasses' memories from FFXI.
