There are very few "bad" .45 ACP JHP loadings though some are better than others. Of the four you mentioned (I'm assuming that the Winchester JHP is their generic white-box loading), the Remington Golden Saber and Winchester PDX1 are the most modern designs and thus would be my choice unless they're unreliable in your pistol. As I alluded to before, however, part of the beauty of the .45 ACP is knowing that even if generic JHP of dated design is all that's available and/or reliable in your pistol, it's likely still at least an OK choice for self-defense.
