I've also mainly used screen for over a decade and it's good enough for one-off sessions, especially if your terminal supports tiling and panes by default, but I feel that tmux is more robust and easier to configure and you get tiling and panes out of the box that work in any terminal emulator. I think it's worth the switch, and I should set up a tmux again for myself too.
