If you ask a 100 different experienced riders, it is entirely possible to get 100 different answers.
I use a B67 (Brooks with springs). It's ok, it works for my particular situation. If I had more seatpost, I'd get a Thudbuster.
I really like Selle Anatomica

There is a ton of other saddles. The width you want depends on how far bent over you are. The closer your back is to horizontal, the narrower the saddle has to be. If you bend over with a B67, the saddle will try to lever your thigh bones out of you hip socket. Not fun.
