Oh man...the more I read about Cresties the more I want one instead of my Leo. But then, I can't touch my leo at all...

MOST leopard geckos are really sweet and handleable and will not try to jump away from you with no warning like another little gecko in question. Leos do need a bit of heat, and like their cages at around 85 warm side. They live quite nicely in a 10gal with paper towel or newsprint substrate, two hides, a water dish and calcium dish. They come in many cool colors and are larger but not unmanageable in size.

Basically, it's all about what kind of care you can provide. If you don't really want the work of a semi-tropical vertical enclosure then go with the leo. If you don't want the hassle of feeding live insects and providing belly heat go with the crestie.
