Zero difference. But I don't live in the mountains. Maybe then there would be a little difference, but if I were to go up a climb 20 seconds slower or something, who cares. I'm not racing. I do have lots of short and nasty hills that drop plenty of people in my group rides, but I'm no slower on them by any amount that's measurable.
