I've tried Mate Terminal as well. It did well. Just took a little more RAM than lxterminal, and I was on some limited hardware at the time.
qterminal is another good minimalistic one. xfce4-terminal as well.
@RL_Dane @redgreen925@fosstodon.org If you're using Wayland, Foot is a pretty good #terminalEmulator. It is incredibly fast to open. Like, if the daemon mode is on (and maybe when not), you're pressing Super+Enter (say) and your finger hasn't come off the Enter key yet and the window is already open.
@benjaminhollon That's cool!
