The grass isn't greener at Samsung's garden. I just came back from 8 years on Android (my last iPhone was the 4), and the two weeks with the XS Max, while frustrating due to some limitations, were a breath of fresh air in terms of speed and battery life. Samsung's android updates are so slow that if they break something it will take nearly a year to fix, if they ever get around to fixing it in the first place. My S8+ was fast and decent on battery. After Oreo? It's sitting on my desk, after a low-medium intensity day at 10%, the last 20% or so was idle drain. The battery has been replaced, as has the screen, and the charging port and it's been formatted.
As annoyed as I am with Apple QC, I'm confident that I'll have an enjoyable experience once I get a phone in "brand new" condition without any chips, scratches, or dust under the screen.
That begs the question, why do these units have chips in the glass or blemishes in the steel? I get glass is fragile, so couldn't Apple do a better job protecting protecting what amounts to a luxury device? Yes, these are tools - but you could replicate 80-90% of the experience with a vastly cheaper android device. Aside from 'feel', smoothness, reliability and security - this is largely a vanity item. As such, even Apple advertises the phone as a piece of jewelry. I'm with OP - there is no excuse for items damaged out of the box. I can believe 15 of them had blemishes. I was willing to put aside some markings on the stainless steel bands due to the PVD process, but glass chips or anomalies are out of the question.
