Stowing these is a problem compared to the usual cylindrical ones, but the round ones are much easier on the boat. A cylindrical fender "rubs" against the dock and boat when a boat rolls in its slip, and if there's a side force from a crosswind or tide that rubbing can be quite hard. In the same situation the round fenders roll vertically back and forth, tending to "rub" less.
One of our local boat painters highly recommends going to spherical fenders (called "scotchmans" hereabouts - often used to buoy crab/prawn pots) to their clients with freshly painted boats.
