I agree with everything Olstyn has said

Personally I find cresties more interesting to watch, as they never cease to amaze me with their acrobatics! I love setting their enclosures up too, I find it more interesting to find various live plants that crickets are less likely to eat though and that the lizards will make the most of by hiding amongst them. In saying that leos are inquistive little geckos as well even though they are definitely lazier lol.

Both make very rewarding lizards to own though whatever you go for
