Corn snakes are pretty easy to handle on a daily basis but why you would need to is beyond me. My corn is in feeding mode as soon as she smells the hint of a mouse. All I have to do is open the freezer and she sticks her head out of her hiding place. So take that into consideration when going to handle a snake. Don't smell like food.

Our ball pythons are still babies so they don't really like us right now.

Overall, I think its on a snake by snake basis. Every snake is different, regardless of species. But I would personally go with a corn or king if you want to be able to handle it a lot.
