I think that the only broad generalizations that can be made are in "what not to get" advice - Do not get gel, or cushy saddles that may feel nice when you first sit on them, but which overly conform and will restrict blood flow a few minutes into a ride.

Leather saddles like Brooks, may require a breaking in period, and even then, may not be your cup of tea. However, there are so many variables with regard to rider positioning, and riding style and body shape that there's going to be a huge component of trial and error involved in finding the "right" saddle.
