Looking to get a colubrid to keep but don’t know which one is best for me

[ballpythonluvr]

I am not keeping ball pythons anymore and I am looking to get a colubrid. I was thinking of a corn snake, California king snake, or milk snake. Are they all relatively easy to keep? I want something that is going to be fairly active and not be a pet rock. I am researching all of them now. Please ignore the angry emoji in the title of my post, lol, I accidentally somehow put it there.
