I've been using the beta channel for ages. Never has been a problem for me. The stable channel is stable as advertised. It's rock solid. ESR is not so much about adding even more stability and more about just guaranteeing long periods without any changes whatsoever in order to cut down on testing cost that big IT departments have for any kind of change.
Insisting on an ESR release on what is effectively a poorly supported type of operating system where every install is basically a snow flake that heavily relies on it's users being able to fix all sorts of weird issues (i.e. every Desktop Linux distribution ever) is a bit weird and overly selective.
I said involuntary testers. The guys who sign up for the nightlies and beta know full well what they signed up for, but not the involuntary testers aka "normal users".
