I see this argument often and while it has some merit fit is not the only thing.
Sometimes it’s just your skin and ahem how much hair you may have.
I’ve been riding enough, and had enough positions on a bike, to know (anecdotally of course) that the fit doesn’t matter.
Im 100% more comfortable with chamois cream. Different fits, saddles, bikes, chamois, etc have never made an appreciable difference for me.
