Get the single flute countersink. It CANNOT chatter(at least in 40 years mine never have),and,you just regrind the flat face to sharpen it. The zero flute has a hole through it and would take a bit more trouble to re sharpen it. Like,a small grinding tip on a Dremel.
I have made several single flute countersinks myself. They have odd angles on them which I sometimes want. Made from 01 drill rod,and run slow,they last just fine.
