Except that they are really, really efficient in terms of pees per (minute × unit area). They are the reason why there is never a queue at the men’s anything like as long as the queue at the women’s at any event at a place where only equal area has been devoted to those two segregations of toilet.
(We need to get over that, by the way. Architects, I promise I won’t feel slighted if the women’s has double or whatever it takes the floor space as the men’s; make it equitable, not equal!)
