Considering I like to wear shorts in the winter any day I like the cold a lot better than hot. In addition, from a running perspective racing in cold weather is about 100x better than in the heat.
Definitely hot for me because I can't really do much outside when it's cold and snowy. (My job is ruined [Landscaper] during the winter until about March
I have lived in both cold and hot places and I find it more difficult living in a cold place- it's so hard to keep warm! But then again when I am living somewhere hot I hate it because it's so hard to get cool. Sometimes you can't win =-(
