Corn snakes make EXCELLENT first snakes, but go for what you WANT and what you can afford, and what your experience level will fit.
If you have quite a bit of free time to work with a lizard, space for adequate caging, and money isn't a big issue, lizards are excellent pets.
I find lizards can be a bit more pricey in the nutrition, initial set up, and lighting departments than your average Corn snake. Not everyone is meant to keep lizards, they have different needs than snakes.
If you don't have experience you need to keep a certain animal, go out and get it. Ask questions, read, most people are really helpful.
Find a local herp society in your area, and meet the members. Many are willing to help you learn everything you want about local reptiles and amphibians, as well as exotics.
