It's personally more intuitive to navigate tabs using iterm and tmux just makes the screen space so limited. If I don't do pair programming is it recommended to just use iterm?
I like tmux because I can do everything without my hands leaving the keyboard. I vaguely recall trying iterm2.<p>Also, tmux is much like GNU screen. I can run a remote tmux session on a server, detach it, then ssh back in and get right back into that same session later (tmux && C-b D then tmux attach)
tmux really shines for me when starting or switching between projects. I can fire up a rails app with a single command and have all the tabs I like ready to go.
