Corn snakes and Ball Pythons are similar in size length-wise. The difference is in the girth. Ball Pythons tend to be wider and heavier than corn snakes.
They both have similar enclosure size requirements
Ball Pythons thrive at a 5 degree higher temperature range than corns (corn snakes hot spot is around 85, Ball Pythons around 90).
The main difference in husbandry is the humidity. Corn snakes do not care whether the air is wet or dry. Ball Pythons thrive better on 60% humidity.
Corn snakes are primarily diurnal, Ball Pythons are mainly nocturnal. Corn snakes are more active while Ball Pythons seem to hide all the time. So, you might find the Ball Python kinda boring.
Anyway, if you feel you can take care of 2 Jaspers, then it only takes a little bit more work to get a Ball Python instead of another corn snake.
One main thing that freaks out new Ball Python owners - there will come a time when your Ball Python will skip a meal. So, it might take a little bit more work and worry when this happens. It's just part of the hobby...
So, yeah, if you think you can handle it - go for it! It is definitely much easier than having a cat!
