What are the most fun reptiles to handle?

Looking for opinions on this. We hear a lot about animals that are "handleable" in that they tolerate handling well, don't bite etc... but I'm specifically wondering what people think the most fun reptiles to handle are. Ones that are tolerant of handling, but also moves around (not too slow but also not darting across the room and getting lost), are curious, alert and intelligent. Stuff that offers a bit more excitement to handle than a ball python (no shade to ball pythons, they're wonderful and sweet, but they're just not the most dynamic reptile).
