The actual seat to your bicycle is your butt, and how well it works depends on how long and how hard you ride. Riding three to five times a week does not mean anything at all if they are not long and hard enough to build up your butt.
Personally for road bikes, if I am in shape to ride, it does not matter what seat I have on the bike at all, but if I am out of shape then I will use one of the thickly padded gel-filled seats which were probably designed for casual bicyclists. None of the small looking skimpy lightweight saddles is going to be comfortable for any normal person unless they are in shape from riding seriously around a hundred miles a week, going fast if their rides are on flatter terrain to make up for the lack of having to pedal hard up hills. I am sixty years old and probably am losing muscle mass, my seat, every year now, but I am guessing because I love to ride fast and hard five days a week my "seat" is still providing good service.
