you clearly have never ridden a bike for hours. Or days.
This is great for 5min ride to the shop and back but for a serious ride is big no. Unless you have 3 feet wide behind.
Saddles are personal preferences and you just have to find the right one and then get use to it since they are all uncomfortable at the begining. If saddle feels great at first it probably means that it will suck in the long rides. The issue with those wide and thick ones is that it spreads your legs too much and rubs your thighs to much. And that stays with you far longer than that feeling of pain from thin, hard, narrow one. And comes back after every ride because your legs are not moving in natural position.
