I find that people generally have their own personal favorites, much like their grandfather drove Fords, their father drove Fords, and by god they're going to drive a Ford. Mine is Castrol. I got that way because of a good friendship I developed with a guy that owned a parts place for Datsuns, where I could get factory parts for half what the dealership charged. The dealer pushed Datsun "branded" oils, and made the claim that anything else could void warranties (back in the days where they could do that). This parts-place guy recommended Castrol products, and I have used them for over 30 years.
You find what suits you the best, and use it.
