I'm pretty stuck on Emacs for Lisp stuff, but interfacing with a REPL from TM would be a step closer for me to give it a shot. Understanding s-exps is next on the list.
I'll have to read more on Visor (or just try it). It doesn't look too interesting at a glance since iTerm is already a Cmb-tab away. There must be more to it that I'm missing.
I prefer Visor for a few reasons. First, I just prefer Terminal to iTerm (especially now that it has tabs). Second, F3 (my hotkey) always gets me Visor; cmd-tab may take more or less key presses depending on what apps I've been using. Third, since I set Visor up to use a different Terminal which runs in the background, so that's one less app to cmd-tab past. Mostly, it's a convenience thing-one F3, and always one F3.
