Buy the iPhone that you want and enjoy.
Honestly at this point, people should be doing what works best for them, if upgrading every year is your thing, do it, life is short, enjoy this thing!
I’m thoroughly enjoying my 13 Pro Max it’s more powerful than I need a phone to be and it does all that I want to do on it incredibly well.
If the 14 Pro Max is a worthwhile upgrade for you get it and enjoy it, looking at the reviews Apple have knocked it out the park as per usual.
You cannot go wrong if something works for you.
I’ve swapped my 13 Pro for the 13 Pro Max this morning as my wife and I have had them a week and she’s complained about the size of it all week. Indeed, get the phone you want I say, I chose last years devices as the deals were too good to pass up and the 14 Pro isn’t worth the extra over it IMHO. Works for me although the Max is far too big and not sure how I’m going to get on with it. It’s bloody heavy too!
