Darkness of course, who can stand to be illuminated to the point one's eyes burn. The darkness is calming and freeing, allowing one to be lost without moving to a location hitherto unexplored.
I hate the light because it limits all the other ways you can experience something and doesn't help you see anything but colors better (in the opinion of someone who doesn't see the difference between HD and standard television who wears glasses and is blinded by the sun when several layers of clouds are in the way).
Overall, darkness is just more amiable from my perspective.
