its very subjective (and often ignorant) to think/state with authority that one oil is 'better' then another. This often comes up with synthetics. Just because one blend may use more PAO or Esters does not make it better. They all are just different formulations (which are proprietary to the blender).

For example Redline can be very shear stable which is great in racing conditions, but has a much lighter add pack: so running it on the street means you need to change it more often. Does that sounds like a smart use of oil and money? Not when there are better add packs and shear stable products out there for the street at a lower cost

Folks do realize the total number Zs and other 3.7L VVT cars out there that get 3-5k stock dealer bulk 5/30 oil changes in them and are perfectly fine?
