saddles typically have different widths, which is super important for comfort.
the width between your sit bones is going to determine what saddle is best for your butt.
for instance, i am of the "wide load" variety, and i am most comfy on saddles with widths between 145-155.
why is this super important??
if you ever ride your bike longer than 10-20 miles, you will definitely notice when a saddle dosn't fit your butt.
if are meant for a wider saddle and you are on a skinny saddle, you wont be sitting on your sit bones, but you will be sitting on your TAINT and this will be painful after a short while.
hence why you will see road bike saddles with cutouts down the middle.
its hard to recommend a saddle without knowing distance between sit bones, but i will say allot of people are comfortable on brooks b17s, because the leather saddle will eventually conform and mold to the rider's butt....eventually. took mine a good year or two
