African Fat tail gecko vs. leopard gecko

So what's the diference between these 2 animals?They look the same except for patterns and color from what ive seen.They seem to cost more though maybe these were just morphs what's the average price for a fat tail and which one do you guy's think is better?

I keep both and the biggest difference in care is that fat tails require more humidity. In temperment, fat tails are much more relaxed and chill, while leopard geckos tend to be a little more high strung. Leopard geckos have been around longer and have more available morphs, while fat tails are relatively new on the scene and their morphs even newer, hence the price difference. Leopard geckos are much more common and bred by big names and backyard breeders alike. In pet stores, it's not uncommon to find wild caught fat tail geckos, as there just aren't as many people working with them yet. Fat tails and leopards are both very hardy and great pets to have, but I know my personal favorite are the fat tailed geckos.
