The BSS is probably heavier in any given configuration and that makes it preferable for some shooters. I have several BSSs and no Win 23s, but based on handling a few, I would think the BSS would be a bit stouter. The BSS will definitely be less expensive to buy and probably less expensive to maintain. In 12 ga, the BSS does give you the option of 30" barrels, max 28" in 20 ga.
