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 use the broadcast, zoom, grouping, and the guake/yakuake style dropdown.
Also it has layout switching like xmonad, ie you can ctrl + space to cycle pane layouts.
