Kryptonite and Onguard seem to be the two major bike lock makers. They each has its rating system of the security levels of their products. It will be interesting to know the correspondence between the two rating systems, e.g. a level "9" in Kryptonite is equivalent to 4 or 5 stars in Onguard?
I think the best way for them to advertise or compete is to invite each other to pick/break the rival's locks--and publish the result for us
