In the following, I absolutely don't mean to diminish the very real frustration and very justifiable anger those of you experiencing these issues must be feeling. But I'm going to suggest that, based on what we know so far, this appears to be a minor glitch in the scheme of things affecting a very small % of units and that Apple will resolve it very soon.
And therefore, those of us who are thinking about buying an XS or Max, or (like me) have ordered one and are waiting for it to be delivered, should not get too stressed. (Yet.)
The source of this stress is reports like the following that suggest these issues are due to hardware and cannot be fixed with a software patch, e.g.

which is based on

a blog post written by someone named Andrew Shepard.
(FYI, Shepard posted an update yesterday to clarify his earlier post:
https://www.wiwavelength.com/2018/09/antennagate-2018-youre-getting-my.html )
Andrew Shepard seems like a really smart guy who knows what he's talking about. But we really don't know much about him. The Tom's Guide article calls him a "radio expert" but based on what? Shepard's blog and twitter feed do not have an "about me" section that lists his credentials. On his Google+ page (people are still using Google+??), he describes himself as an "armchair engineer & communications policy wonk" who attended the University of Kansas. (Does he have a B.S.? Masters? He doesn't say.)
Because we don't know more about his credentials, and because (as far as I know) his findings have not been replicated or corroborated by other, independent, credible sources, we should take his analysis with some healthy skepticism.
It's certainly possible that Apple screwed up by using a crappy antenna design or that Apple chose poorly performing antennas on the XS/Max models, in which case Apple will have to recall or replace millions of $1000+ phones.
But until Mr Shepard's analysis is confirmed by other objective independent and reputable sources, I think it's far more likely that the issues many of you are experiencing are a horribly frustrating but ultimately fixable new product rollout glitch, and that Apple's engineers are busting their asses to get a fix ready to push out.
We don't know how many XS and Max models are having these problems, but it's very likely a tiny %. If Apple has sold 1 million units since launch and 10,000 unfortunate people are having problems, that's 1%. Apple's probably sold much more than 1 million, though I don't think we can know how many people have units with these issues. But if the number is around 10,000 (justifiably angry) people, that would account for the volume of activity on forums discussing these problems. But again, if it's only 1% or so, then those of us who've already ordered or are thinking of buying an XS or Max are very likely to get one that's not experiencing these problems.
Also: some of you have reported similar issues on older devices since updating to iOS 12. Again suggesting that the problem is due at least in part to something other than XS/Max units having defective or poorly performing hardware.
Lastly, if Apple had indeed screwed up and put bad hardware in its XS & Max models, it's overwhelmingly likely that Apple's stock would have taken a hit. Big institutional investors like insurance companies and pension funds hold huge amounts of Apple stock and have armies of experts that analyze every scrap of information to determine whether to buy, sell, or hold. If there were an unfixable problem with the XS & Max iPhones, I'm pretty sure they'd be all over it as they have far more to lose than any one of us.
For all these reasons, and until other sources besides Mr Shepard come out with corroborating information, I'm inclined to not worry too much that the super expensive iPhone Max I ordered has hardware defects that would lead to the kinds of problems many of you are experiencing. I am guessing that Apple will resolve this issue in the near future.
Of course, we should all be extremely prudent and (a) report any issues to Apple so they get a sense of how widespread these problems are, which should give them a greater sense of urgency to fix them and (b) return our phones to Apple if the issue isn't resolved within the 14-day return window.
