Zinc has a bunch of benefits besides just improving scuffing on cam lobes. I run a small amount of additive in my 6.0 diesel since it does a better job of protecting any metal on metal surfaces and since some have experienced roller lifter failures in these diesels, hopefully my chances will be lower as a result. I also run it in my Mastercraft ski boat for similar reasons.
Lower zinc levels were mandated to prevent damaging catalysts on vehicles not because the non-zinc substitute additives work better; most oil Mfgs would rather use more than they currently can to improve their oils performance

It's not just adding zinc, but how it's formulated.
I was running Lucas Classic, but in the scientific testing, it didn't fare so well. That's when I switched to the Valvoline VR-1 Racing Oil. In the tests posted on this site, it ranks near the top.
Most surprising to me was the tests showing that Edelbrock zinc additive ruined more cams than anything else!
