Terminator comes close, but to be honest, iTerm2 still beats it with its user friendliness and features.

It's really interesting how OS X is the one that has a terminal emulator with the most features out there.

iTerm2 now comes with 24-bit colors, command completion popup, notifications, triggers, profiles, mouseless copy, split panes, search, and you can even have inline images/gifs all out of the box with zero or minimal configuration required. That's just awesome.

All of these features and iTerm2 still feels much faster than Terminator to me.
