I like both of them, but HIMYM is more my style, despite my love of most things nerd or science related.
However, I've watched all of HIMYM, so now I'm working my way through BBT. I think I watched too much of it. Last night I had dreams about the manga Berserk, except Guts was Leonard. Hilariously disturbing.
