Well, some of the RP products, as you are aware, do have API licensing, just not all. From what I've come across in my research, no, RP isn't perfect for everything, nor is any brand or grade, for that matter. They have some oils that have higher amounts of ZDDP for those who look for that. They have some SM for those who want that.
As for those who disapprove of marketing gimmicks like horsepower gains, well, I disapprove, too. All the oil companies do them. Look back at some of the past synthetic oil marketing campaigns. They were ridiculous. Even now, we have all kinds of fancy claims.
I'm not swayed by four or eight times less wear, or Las Vegas taxi tests, or huge horsepower increases, or niche wear test claims. In fact, I'm more than likely to attack such claims, even if such claims are made by a brand I use regularly.
Royal Purple makes fine oil. So do SOPUS, Exxon Mobil, Amsoil, RL, BP, etc., etc. Who makes the best oil? That's a loaded question. One has to choose the most suitable oil for one's application. Anyone who claims that one oil is simply the "best oil period" is talking through his hat.
Very well said.
