Sorry, forgot to mention either way I'd go with a Pro for the better camera battery, and refresh rate. So it's basically between 13 Pro (Max) and 14 Pro (Max).I’d go refurb 13 Pro over a 14. Nicer build, extra camera, pro motion display all well worth it. Have a look on GiffGaff. 13 Pros are currently £799 and tend to be as good as new. No quibble returns if you’re not happy.
Thanks
