To add a little more to the history, I made the switch from rvm to rbenv when rvm broke under me (I can't remember now whether it was `cd`-hooking or rubygems-bundler which broke the camel's back). I made the switch from rbenv to chruby when rbenv's shims broke. Chruby does so little that there's almost nothing to break, so I've stayed there.
