I started with screen, but moved to tmux around 5 years ago. For me, the sell was in custom layouts, and the no nonsense screen splitting. I usually work on several different project types, and have a scripted layout for each the of project types. This makes getting started in the morning instant.

Tmux is great, but only after customizing it and making it your own, and this can take a fair bit of time. If you find yourself shelling into remote servers you don't control, or want to use it on Windows prior to Windows 10, then screen is probably a better choice. While tmux could be used on windows through cygwin, I never found it to be stable enough for day to day use.
