Here is the reality, it is much more about branding than about the actual oil itself. For instance Refiners like Shell and Chevron make great oils, but they, or others with license, often package that same oil in other brandings. Regardless of branding the oil is made to an API specification and it will have an API spec on the container. I use Rotella T, now T4 because it's good oil and available almost anywhere. Rated API Spec out to the latest spec which includes all the previous specs. So, just get an oil that meets or exceeds the API spec recommendation for your engine. Just look right there on the container for it. Regardless of where you buy it if it meets the API spec you are good to go and chances are it actually originated from the same refiner.
I did not realize my Delvac was made by the same refiner as my Shell Rotella and Chevron DELO but even if it were, you omitted the fact that quality oil is largely dependent on the choice of base stocks and proprietary additive packages. It is my understanding that the Blending & Filling facility is where the various brands might have common origins but each went through at a different time than its competitors to achieve its desired properties.

A blind VOA will typically be unique enough for a tribologist to identify the brand & type.

I am not saying one is necessarily superior to another and I am not defending any particular brand loyalty, but they are not all the same with only a different color container.
