I used screen for about a decade before switching to tmux. The biggest immediate benefit was that terminal configuration across systems was much less brittle. My backspace key backspaced, color consistently worked, etc. Over the past 10+ years of tmux use I've become increasingly more sophisticated in my usage (in particular 1) nested tmux sessions, 2) heavy use of the kakoune text editor's tmux integration), yet my .tmux.conf file has all of 15 lines of content. One other thing: tmux has yet to crash on me, but screen certainly did so numerous times.
