The universe we're currently inhabiting right now. Of course it's fictional. Real life would presumably make some kind of sense.
Okay, okay, being serious:
The Magic: The Gathering multiverse (once called Dominia, but that term seems to have fallen out of use now. There's Dominaria, but that's one of the central planes within it) is pretty sweet and nicely varied, even if the story's been flagging a bit ever since Apocalypse (Phyrexians again? Really?)
The world of Gurren Lagann is cool simply because you literally can do ANYTHING with sufficient force of will.
In terms of great places to live, though, I'd have to go with Lunar (from Lunar: Silver Star Story, Eternal Blue, etc.) Most of the sentient inhabitants are pretty good-natured, medical treatment for pretty much any condition is free and as easy as touching a statue, unlimited cash is available simply by beating up hostile monsters, the primary religion actually encourages drunken revelry, and I could study magic and hang out with dragons.
