I think the lubelocker is a quality metal core gasket, but it's not like a newer factory GM gasket for a trans pan or the newer one piece oil pan gaskets that are thick embossed silicone with a metal core and with thick washers that somewhat prevent overtorquing, those can seal more issues than a lubelocker, I know what you mean Rick.
With a good quality pan either would work fine, with a bent up pan you may struggle with both but the GM has a better chance. However, I don't think I would spend $90 on a gasket if you can get a machined cast high capacity pan for a little over double that.
