I have to agree. Pre-Cataclysm Ivalice easily gets my vote for being the number one spot to live. You get everything there. A huge, sprawling world, most of which is still unexplored. Friendly, lively cities. A world which isn't actually out to kill you...
Seriously, Ivalice is the only world which is safe to live in. In all the Ivalice games (save Post-Cataclysm FFT), there hasn't really been a threat to the world itself. The Occuria are jerks, but they aren't as all powerful as they seem, since they primarily occupy themselves with a couple countries and their own interior power struggles, and don't seem to bother with actual tyrranical control the way FFXIII's fal'Cie do. The Neukhia may be a valid threat, but the whole structure of the seals and the Grimoires makes it a much less pressing one, and it falls further off the radar because of the way the primary plot of FFTA2 felt so unfinished.
Ivalice also has the advantage of not being elitist. Your characters are strong, but the focus of the Tactics games clearly shows that such strength can be acquired by anyone, while in most games, you are a chosen hero type person. You get to join up with a clan to get you help as you fight baddies, and give you a lot of friends to talk to while you wait for the next mission.
For me, Ivalice easily tops the list of best places to live.
