Mosh is excellent. It lets remote sessions survive (well, automatically and transparently recover from) disruption that reliably kills ssh.

I basically don't use ssh at all any more for interactive sessions, because I'm sick of a few lost packets on wifi or a weak cell signal dropping my connections and forcing me to start over.

Tmux, I used to use and eventually abandoned. I decided I didn't need two keyboard-based window managers (I use Spectacle on Mac) and the one that was only for shells was the one that could go. I have replaced it with nothing, so far, aside from that I just open more Terminal.app windows now (I also used to use iTerm2, for years, until it dawned on me that I was using exactly nothing in it that's not also provided by Terminal.app, and the latter's got better input latency, so I was suffering an extra installed program and slightly less responsive typing for no reason at all)
