I'm guessing the merits of fans and bulbs have been discussed/debated/argued in the past, but since I recently began to replace most of my bulbs with fans, I'm curious to know what others prefer and why. For instance, I think fans use less soap/cream and distribute the lather more evenly than bulbs. Of course, I have no evidence to support this other than my own subjective experience. So what's your preference, assuming you have one - and why?
