Term, Xterm or Uxterm?

I'm an average home user, but still sometimes use terminal for simple tasks. When I type "terminal" in unity, it offers me three choices - but what`s the difference? I hate always choosing randomly and thinking about what I did.

Terminal is, in Ubuntu default software, the gnome-terminal. XTerm is... https://en.wikipedia.org/wiki/Xterm. UXTerm is XTerm with support to Unicode characters. The main difference between XTerm and Terminal is that the gnome-terminal has more features, while XTerm is minimalistic (though it has features that are't in gnome-terminal, but they are more advanced).

If you are using Ubuntu, you should also have gnome-terminal installed. For Kubuntu the default terminal is konsole, and for Lubuntu is lxterminal.

All three are good choices.

To be Desktop Environment independent as much as possible, I would choose lxterminal.

xterm, and uxterm are good but they use ugly looking fonts, and pose some problems in regards to keystrokes (see How do I set up hotkeys for a xterm?).

The default is "terminal", which is gnome-terminal.

You can also summon one with a hotkey ctrl-alt-T
