Completely true about the opinion side of things, but as shown and documented iOS is many times worse in terms of the number of issues that has befallen it on the latest release. So by that measure its "factually" worse, that's not an opinion, bur rather a measurable metric regardless of preference.
Maybe. In this thread or another someone listed a ton of iOS 11 issues. I hadn’t experienced any of them on my 7 Plus or X and I am sure I’m not the only one. And it’s not even close on my iPad Pro. Everything is faster for me than I was with my MacBook.
Either way, as we can agree. It’s opinion and comes down to personal preference.
