There's subtile difference between terminal emulators (terminator) and terminal multiplexers (tmux, screen), mentioned elsewhere [0]. IMO the main difference: With tmux, your sessions can be separate from your terminal instance. Meaning that if your terminal dies for any reason (e.g. X dying), and you've set tmux up correctly, your session will still be there and all you have to do is (re)connect.

The other reasons are probably more personal. The initial tmux learning curve is steep, but once you've got it, it rewards you with a super fast workflow that suits you. I know this sounds extremely stupid, but the "hacker cred" is large with tmux. I got hooked on tmux by a coworker who used it and ruled. I've never seen that with terminator, although it should be equally possible.
