Konsole, but only because I’m on Plasma. I really don’t rven like it that much, but… well, it’s a terminal, it does terminal things so I’m more than OK with it.
On xfce, I would youse xfce-terminal.
anything is fine as long as basic stuff works - like ctrl/shift+insert (tho it’s a thing I had to manually setup in Konsole 😅)
