If you have Macs, it’s pretty hard to beat the integration between iOS and macOS worlds. I was pissed about the lack of a headphone jack in the iPhone 7, but wanted to upgrade from my 3 year old 5S. I went with a 6S right after they lowered the price $200 and so far I’ve been pretty happy with it.
If you have PCs, I think the iPhone is becoming increasingly less compelling. Unfortunately Google has given up on “don’t be evil” and is getting creepier and creepier with their spying^h^h^h^h targeted advertising.
