Difference between xfce4-terminal and exo-open --launch TerminalEmulator

Question

I've come across these two and it seems to execute to the same terminal. Also if there is text for it somewhere, I would love to read it (I've found this: link but doesn't exactly explain what the difference is, nor can I find why there are two).

Answer 1

The command exo-open --launch TerminalEmulator will launch the preferred terminal emulator, which may or may not be xfce4-terminal. The preferred applications are set in Settings Manager > Preferred Applications.
