I firmly believe that Mobil 1 5W-30 and 10W-30 are sub-par synthetic oils.
And GM disagrees, and that's why they stuck it in the ZL1. Honda disagrees, they put it in the RDX. But hey, you are entitled to your opinion. It doesn't match that of the manufacturers who put millions into R&D and testing, but who cares.
Mobil 1 has brand name recognition. That's the largest reason it's used as factory fill in those vehicles.
Pennzoil Platinum 5W-30 is an outstanding oil, is likely better than Mobil 1 5W-30, and it meets the specs for both the Corvette and RDX. Do you ever see that being used, and bragged about being factory fill by the manufacturers? No. Sometimes a recognizable name means more than actual performance.
I think they're all girlie oils. Redline is a "real" man's oil.
