I think its not so much an issue of riding position, as it is time in the saddle.

If you are riding for hours at a time, then the pressure and rubbing of a soft saddle can be brutal. A firm saddle that will support your sit-bones yet does not rub against your naughty bits is a god-send. If you are not spending much time on the bike (and more so if you are fairly upright) then people seem to like cushy saddles.

Remember its a saddle, not a seat. You sit on a seat with all your weight. So, I want lots of cushion in my car seat. But a saddle is used as a place to sort of lean your butt. And since your legs are moving the whole time you really want it to interfere as little as possible in that motion. I want it firm and slick. Brooks are great in this way.

A Brooks is not wonderful to sit on. But it is, for a lot of people, wonderful to ride on.
