I'm pretty lucky in that I find most saddles of a particular style comfortable...my various bikes have Selle Italia boost SLRs, Pro Stealths, Fizik Argos, etc. As long as they have a cut out and are somewhat contoured around the sit bone area, I find them comfortable...even when they're different widths.
Out of all the stock saddles I've had, the only one that I thought was absolutely terrible was the Fizik Arione. That literally felt like sitting on a 2x4, and it would make my junk all tingly.
