If you are used to keeping snakes, then yes, a beardie is high maintenance. Much more work than a ball python, but also very rewarding. They are very inquisitive and funny to watch.
When it comes down to it, it's about what you like in an animal! Everyone is different in what they like about herps. Also, make sure whatever you get is a responsibility you can handle. For example, bearded dragons need to be fed multiple times a day, poop cleaned every day, and veggies prepared daily, so you have to make sure you have the time to invest in the animal before you buy it.
My personal vote, as usual, is for corn snakes. Out of all my snakes I think my corn is my favorite. (Shh, don't tell my BP's!)
