6S felt like a quantum leap from every other phone before it and I’m still using one too. I can’t nail it down but there was something perfect about the size, speed, UI where using a phone stopped feeling like messing with a gadget and became pure information retrieval or communication. Trying every other iphone afterwards I have felt no need to upgrade.
