When I made the switch from screen several years back, tmux didn't need a patched version to support vertical splits, which was nice. Other things included better support for scripting, nicer configuration, and better mouse support and scrollback behavior by default. Screen may have caught up a bit since then, but tmux seems to have a more active community and generally faster pace of development.
