Nebudis...oh shitza!

[Dani Hyrosha]

I like to use Nabudis to level once I get to where I can live that long. Make sure when you do that though that you are always near a door you can run out of in case things get too hot.

There are some good hunts to be had in there, and the best armor in the game is sold by an NPC hidden in a corner if you can find him (I can't remember where off the top of my head)

There are several things to do in Nabudis that are completely optional. There are two marks. There is an esper. A really good one, too. There is also the aforementioned merchant who sells the best armor you can buy. And finally, there is the legendary zodiac spear. Oh, and there's also a rare game in there, too.
