Well, your reply has sent me off looking for the science of grease.

My findings:
Grease is made of oils, thickeners and additives.
Each component is chosen for a specific purpose depending on operating conditions/criteria.
Oil must be able to provide proper lubrication under operating temperature and humidity. Must be durable.
Thickeners, of which Lithium is an example, are used to increase the viscosity of the grease to the point that it will not separate into it's components (stratify).
Additives, of which Molybdenum Disulfide is an example, are used to increase lubricity, stability and other desirable effects. Moly is used to add lubricity under loads and can spin out of the grease at high speeds.

I was comparing apples to oranges. Yet, I still feel that Moly infused grease is good for wheel bearings. If it is based on Lithium, which also has excellent high temperature tolerance, and has Moly added then I think that would be a good combination.
