They all meet the same API requirements and there is absolutely no way to prove one better when it comes to wear.
Well, for the average driver - this is true. John Worker and Sally Housewife both drive Toyota Corollas 23 miles one way every day, and use the cheapest API-SN oil there is, and both cars are traded at 180,000. They will never, ever, ever tell the difference between any two oils.
For a car that does track days, or a truck that pulls a lot of heavy loads (very high piston ring pack temperatures) there is definitely a difference.
