Impossible to say since bottoms are so different. The best you can get are suggestions on specific designs, materials and/or form factors. Bottom comfort is also a combination of seat design, height/angle and fore/aft positioning. Even a perfect saddle can still may not feel right if one of these things are not in perfect alignment.

Like shoes, bike manufactures really need to pool their talent and come up with a better way for consumers to narrow their choices. My guess is, they really don't have much motivation to make any improvements here. Good luck.
