Hands down WOW is one of the best well-rounded games ever. What's not the like?
- Questing system removes the XP grind
- Grouping is encouraged and often done by many players
- A rich history for all races
- A fun environment to play in for all races
- eight playable races
- A class system that actually works (albeit some class tweaks are needed for PVP)
- Lots of high-end content
- Epic and CTF Battlegrounds for PVP'ers
- Loot!
...with more on the way!
I've played Ultima Online, Meridian 59, Asheron's Call 1 & 2, Everquest, Dark Age of Camelot, Anarchy Online, Magic: The Gathering online, Star Wars: Galaxies and more and of all these World of Warcraft has been probably one of the best experiences thus far.
Warcraft has a RICH history and story. It's been in progress for 10 years. If they could just pause, step back, and concentrate on monthly story content that progresses the story forward, then we'd be in complete MMORPG bliss.

I'm hoping for something similiar to the monthly story content Asheron's Call has.
