You can't be told about how cool Exalted is; you have to be shown. </morpheus>
But seriously, the game's an eastern fantasy-based system that incorporates a lot of anime-like systems into a very rich and detailed world. All of the splats from WoD are there in some fashion if you squint a bit, and there's so much lore that it's one of the fullest games I've ever played. Plus, you get bonus dice for describing your actions in a cool way (stunt dice). The character types (Exalts) are all very different from one another with a lot of history built into them.
Redemption's a big theme for the Solar Exalted, who went crazy at the end of the First Age and started committing great depravities on humans and other Exalts alike. They were ousted by the Dragon-Blooded (Terrestrial Exalted) who seek to remain in power. I'm not sure about 3rd Ed, but in 2nd Ed, the leader of the Dragon-Blooded had just come back from the Yomi Hells and was basically made into an evil, evil creature.
Protecting creation is another big theme, since you've got the Deathlords and their Abyssal Exalted, and the Fair Folk on the edges of Creation in the Wyld. So you have to be a big damn hero and save the world, more or less. It's just fun, and doesn't have the grind that D&D does, nor the inherent WHY ME that WoD does.
