What's your preferred terminal?

I'm using Gnome on Fedora and was wondering what terminal everyone's using? When I had a Mac I really liked iTerm2 and was hoping to find a suitable Linux version, but so far no such luck. I've tried Guake but I can't get the F12 binding to work.

Preferably, I'd like to find a terminal that can display system stats the same way as iTerm2.
