How do I replace SuperSU with a different superuser app?

[ianmathwiz7]

I've been using SuperSU as my superuser app, but I want to switch to using ClockworkMod's app instead. Is the procedure as simple as granting the new app root privileges in SuperSU, then uninstalling SuperSU; or is it more complicated than that?

(For example, I notice SuperSU has a cleanup option for if you intend to switch. What does that do, exactly?)
