At least on this forum, everyone is NOT returning to the stock seat. Some may be selling their aftermarket seats due to the bike being sold (and they can get more separately for the aftermarket seat) or they just we're not satisfied with thie aftermarket choice.
My advice to you, is to take a several hundred mile trip and see if you are comfortable on the stock seat. If you are not and have tried less financially invasive solutions the thereafter i.e. Sheepskin, Beadrider, Air Hawk, etc... then start asking about the different aftermarket seats and back rests.
