I've never had a feeding issue with a corn, their requirements are easier than ball pythons ( all mine corns are in tubs on a shelf in my snake room. Since the temps in my snake room are around 80-85, no need for more heating for them ) and they also come in so many colors and morphs. But they are super squirmy and very active.
My 5 year old handles most of the care for our corn snakes, as she says they are hers ( along with my new pied) so you can see they are very easy to deal with.
I think whichever your friend chooses, they will be happy.
