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.
It doesn't matter to you. There's all sorts of reasons it might matter to other people like right click support, SSH profile management, how it handles tabs, and on and on...
