So for me, my partial feeling go like this:

Leopard Geckos:
Super cute (like Lgray said, who couldn't love that little face?)
Much easier to house
Cheaper

Bearded Dragon:
Awesome personality
Still pretty cute :p
Bigger
Better handling
They look awesome xD

The bad thing though is the expense of the Bearded Dragons. I'm saving up a lot of money this summer, but I'm not sure how well I'll be able to handle caring for a Corn Snake, a Ball Python and a Bearded Dragon at the same time. Looks like I'll need to mow some extra lawns.
