I started using tmux several years ago because it had better script support than screen did, at that time. I also liked the session/pane/window handling better (customization made a lot more sense to me, as a vim user), it supported some plugins that I really liked, and the ability to sync panes was a cool feature that came in handy sometimes (grepping logs for load-balanced applications), but I honestly rarely used. But I couldn’t tell you now, without some digging, whether screen supports all these features today, or if it’s perhaps even better than tmux.
