I had a couple of Bearded Dragons for years. We almost never took them out because it didn't seem like you could interact with them much. Lizards don't sit still as well as snakes so you can't just hang out with them, you've got to pay attention or else they may jump or climb down.
When I've had snakes, they get handled a lot more because they are happy to just sit on you for an extended time. You can put a smaller snake on your hand/arm, or a boa around your neck/shoulders and they'll stay there while you watch TV or type on the computer.
Obviously this is in part a personal preference issue but for me there's no comparison, I find myself interacting more with snakes than lizards and I'm really enjoying my first Carpet Python I recently picked up.
Just to point out, you NEVER take a fish out and handle it, and yet people don't seem to think that makes them a waste.
What I would recommend is that you go to a reptile show. See different animals in person and handle them, this will give you a better sense of what you like and whether you comfortable handling them and how exciting it is or isn't for you.
