I did get the 8, because I was moving up from a 5. I had pretty poor battery life on the 5 somehow - it would drop to 1% from 20-30% instantly! And performance was manageable but not great with the latest iOS version and apps (like Google Meet which is needed for work).

Overall, I went for the 8 believing it will have good overall standing in the long run, in terms of performance and battery life, as opposed to the 7.
