I'm skeptical that a change in saddle would make a huge difference for the average rider. I personally find that my comfort on the road bike correlates to how hard I'm working - active group rides I'm fine; noodling around with family on the same bike is a lot less comfortable. The only difference I can see is that I'm putting way more weight on the peddles in the first case compared to the latter.

I imagine your average rider is probably a lot closer to noodling around than a group ride.
