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.
I've really grown to like yakuake. I always have a sorta "main terminal" where I have a tmux session going and now I do that in yakuake so it's available on all desktops and easily put "out of the way" when I don't need it.
