I'm going to be the odd man out and be the only one to vote "too hot". Here's why:
I've been both, but I seem to cool down from being too hot more easily than I warm up from being too cold. People here speak of warming up easily; I don't warm up easily. Even when confronted with warmth after being too cold, I tend to still feel chilled and my nose, toes, and other extremities still feel cold to the touch and it's unpleasant.
With warmth, however, one step into an air-conditioned room and chances are I'll be too cold within several minutes. I seem to cool down fairly quickly and easily.
This summer I went to Denver and at one point, I had to walk 2 miles in 100-degree weather, no shade, I had had no sleep the night before, my whole back was sweaty, and I had had no water. I remember thinking "this is crazy; this is the worst thing I've ever done." And yeah, it was unpleasant. But at the end, when I got into the air-conditioned store and had some ice water, I instantly felt rejuvenated and cooled down. It was one of the greatest reliefs I had ever felt. It would've taken a while of shivering and trying pointlessly to warm my nose or my hands or something if it had been cold I was feeling and not heat. When I remember having P.E. early in the morning when it was 30 degrees, in shorts and a T-shirt, all that harsh cold air going in my lungs and the incessant shivering, the Denver experience seems nice by comparison.
