Saddles are the most personal thing about cycling... what works for one does not necessary work for another. Some people need very narrow saddles, because of physiology and some need wider. Some need longer and women generally need shorter.
That said: I use two saddles - on the road bike its a Terry Butterfly Ti. On the mountain bike its a WTB SheSpeed. Both serve a different purpose for different styles of riding. The WTB is longer to accomodate moving back and forth on the saddle; the Terry shorter because I generally don't move around alot on the road bike. The Terry also is cut out in the middle to relieve pressure to girly parts.
