Unlike uncomfortable shoes the saddles have a point, not chafing/ allowing for the pedalling movement while also supporting part of the riders weight.

Wide/cushiony saddles prioritize comfort of the latter point over the former. They will support more of the riders weight more comfortably, while neglecting the comfort of the movements of the rider. So on shorter and easier rides the cushion saddle is fine, the longer you go the more such a saddle will cause discomfort.

If your saddle works for you by God keep using it, im just trying to explain why other people use different ones.
