I agree with everyone else. Pick what YOU like.
I would pass on them all but I'm also a fan of really reduced butters/lessers. I second the notion of researching. Look on here, fauna, kingsnake, and on world of ball pythons. See what trains you like in a butter/pastel butter and then wait a bit until after clutches start hatching (late summer for the most options) and then pick one that has the qualities you like.
