Regular and Fast or Gentle and Slow?

I just went to do some laundry and had to adjust the setting on the washing machine. I'm not very esoteric(that would be an understatement of gigantic proportions) but it inspired me to start this thread in the spirit of the fine My Miss Storm Cat threads that appear here.
So which do you folks prefer? Regular and Fast or Gentle and Slow? Or do you like to do a load both ways?
