"Better" oil? How would you know what is better? What defines "better" in your application? It seems that $$$ = better, from your comment.
Until you test the oil in the application, and see how it performs, then you have no benchmark for judging any future success or failure of any alternatives you try. I suspect this oil would do an outstanding job. So will many other brands.
Rather than just buying something based upon a hunch and guesses founded upon rhetoric, why not try this concept:
1) establish your maintenance plan operation criteria; perhaps follow OEM guides? Alternative ops?
2) establish a baseline with the current product; test with UOAs over several successive OCIs
3) establish condemnation points; use either ones directly attributed to PACCAR, or get some reasonable ones from similar industry choices (Cummins, Mack, Volvo, etc)
4) select reasonable candidates for alternative testing; do UOAs here as well
5) compare/contrast the results of UOAs, relative to the cost of the choice; use ROI as your guiding mantra
Or, just pick something people push you towards; sort of an oil-de-jour from the brand/grade bigots here ...
