I’ve always just used konsole or gnome terminal. Never really looked into what else is available. Tried cool-retro-term the other day, but the novelty wore off pretty fast for me.
Curious to see if there’s a terminal someone swears by and refuses to use anything else.
Realistically, no difference.
They are called emulators because “Terminal” used to mean a full-screen text interface to a mainframe. The functionality has carried on, which is why terminals behave pretty much the same on any platform. You don’t use your system’s regular text fields in a terminal emulator, for example.
