There's no such animal as a SS Police 3. As for the differences between a SS Police and a G-10 Police 3: IMHO, the Police 3 is a better slicer, the Police has a more acute "splinter picker" tip, the Police is heavier, the Police 3 has a longer blade and a 50/50 choil. As with the question of serrated vs plain edge, which set of characteristics is "better" will depend on what you're looking for in a knife.
