"Most difficult purchasing decision in years". It's just premium look and feel vs premium phone...
If you value appearance above all else (or a slim fit in your pocket), you get the Air. If you want the best phone, you get the Pro or Pro Max. If you want the best value, you get 17, and it's not close. Where's the challenge here? Coming to grips with a reality that you buy electronics for vanity, not capabilities? If you're considering a Pro because you want the capabilities of the Pro, there's no reason to be considering the Air, as the base 17 would be a better alternative to the Pro. It's both more capable (outside of missing some ram) and less expensive than the Air. The Air is the third best option from a capabilities perspective. Not complicated.
The 12 and 13 mini generated more challenging purchasing decisions (that rarely went the mini's way unfortunately).
