the iterm mode allows one to create, split, resize remote terminals as of they were native terminal windows, instead of all of them being contained within one terminal window and controlled using completely different keyboard-only shortcuts (via tmux)

does this make it faster? or is it used for the native feel

Mainly the native feel. For example, you can use standard Cmd-based keybindings to control tabs and panes, and get smooth mouse scrolling in each pane.
