I know one iPhone 8 user who was very happy, until he mistakenly upgraded

Why was that iP8 user unhappy after an iOS upgrade?
My iP8+ is currently up to date with iOS 11.4.1 and I have yet to
experience any
problems. In my hands it has been my best iPhone to date, and I am not
lured by Face ID.

ability to use something until you become fluid with the new system.

in other words, you're blowing smoke.
