In the end the OEM or stock saddle never matters unless doing a non-riding display bike that needs to be period correct. In the end get a saddle that is comfortable for your rear end and your comfort. I find those heavily padded gel saddles to be quite the opposite of comfort because they offer soft padding which gives no support so you sink in and create pressure points and those pressure points equal pain. Also a super wide saddle will make it harder to pedal on a non-super upright bike and can cause chafing issues as well. A good saddle will support YOUR sit bones well and can have some padding but you want good firm padding and you might have to adjust it fore and aft, a few degrees of tilt or not and the height and then ride it for a while to get a real sense of things. A lot of people did like the old Spesh Body Geometry saddles but some of their new stuff is quite nice and my rear end happens to like Ergon quite a bit (also my hands prefer it) and the Brooks Cambium line has been my main saddle of comfort as it has flex instead of padding and is now fully waterproof and can look nice on some vintage bikes as well. However you might find something different.
