If you want to help test the next release(s) of Debian, or want the newest packages (with the potential for some occasional aggravation) use "testing" or "unstable". If you want nice, boring consistency, and predictability, use "stable", and take a couple of steps back from the leading edge... :)
But the removal of packages is a bit drastic even for testing (not for unstable though).
