Any name brand 0w-20 synthetic is probably as good as any other. Anything beyond that is just personal preference. Besides, how would you ever know, even if there was a definition of "best", which there isn't? Marketing hype is not real world performance.
By the time you might figure out that one oil is better than the other in your subjective opinion, your car has been traded for something newer, anyhow.
In simple terms, brand name makes no difference except for the one that I have picked for my vehicles.
What makes a difference is your climate, driving habits and maintenance.
