I think it depends on the bike, but the Swift has been my favorite. I also had a B17 but I gouged the crap out of it when I was sideswiped by a car and crash and burned my near mint 85 Schwinn Le Tour Luxe back in 2019, that saddle was ok, it was comfortable but the Swift was better, probably because the leather is a tad thinner on the Swift, I think.
