I have kept/keep all of the above. I say cresties hands down. My reasons are: They are cheap to keep. One bag of 10 dollar powder food last months. They don't need to eat bugs (but they do enjoy it every now and then

). They require no special lighting or heat. So low maintenance but still a "friendly" animal. And you can make their enclosures look soo nice with live plants and branches.
I also love BTS but they do require a little more attention and they hide alot.
Good luck on whatever you decide on
