These are all good oils and it uxusllly comes down to availability and price.
I frequent BRITISH car shows and there is usually someone selling oil. I picked up a case of Kendall 20w50 racing . At the last show.

According to this thread that the Porsche 10w60 has 1,000ppm of zinc, compared to the 1200ppm in Brad Penn 20w50 or Mobil 1 20w50. It's thinner than what was specified in the 80s. Gives me the *******.
Manufacturers change recommended oil specs all the time to reduce inventory. BMW seems to go through this debacle regularly. I don't think Porsche has much interest beyond selling oil and replacement parts. Similarly, the intervals recommended often come from how often they're willing to change the oil on their dime, not necessarily what will get you past 200k miles without opening the motor. Trusting blindly in a brand is folly.
A random fun bit I learned recently is that calling an oil "synthetic" is mostly just a word unless there is greater specification...
More than anything, just change whatever you use regularly and drive the car...
