the material and manufacturer are secondary concerns.
whether a saddle is right for you depends on:
A) your sit-bone width
B) how your sit-bones fit into the the wide part of the saddle as determined by your riding style i.e. how angled your sit-bones lay due to bending over the bike from your hips.
a time-trial or triathlon rider is bent over the bike greater than 90° and reached fully forward on aero bar extensions. this type of rider wants their saddle to match their sit-bone width almost exactly and will prefer a more flat-top than a contoured profile.
a casual rider on a fully upright bike like a beach cruiser or Dutch bike will have no angle on their sit-bones and will need around 4cm outboard of either sit-bone, which is to say: sit-bone width in mm + 80mm
you can see from the pic he chose for the embed that he’s chosen an increment halfway between “sport” and “race” i.e. 1.5cm/15mm for a total addition of 30mm wider than his sit-bone width.
he uses aluminum foil to measure sit-bones but I got better accuracy using corrugated cardboard, personally.
none of this will matter so much if you don’t have your seat raised to your proper height for proper leg-extension. you want almost full leg extension at the pedal’s lowest point but with a slight bend always in the knee.
NEVER LOCK OUT YOUR KNEES. also don’t slide left-and-right over the saddle to achieve leg extension, either.
