I think the point is for a saddle to be comfortable for a long ride, your weight should be on your "sit bones" (basically where your hipbones get closest to the saddle) and not on your <euphemism> soft tissues. So a saddle like the Gel Flow above might be great, because you are still mostly contacting via sit bones, and the padding just cushions them a bit, while a bulky padded saddle may feel comfortable when you first sit on it, after a few miles you'll be in agony.

I'm a fan of an unpadded Brooks, but they really don't work for everyone, and they are not cheap though I believe have a good resale value.
Fizik have a saddle test scheme where I believe you can pay a deposit and try out different saddles. Might be worth looking for a retailer near you that has them.
