The main rear camera on the latest iPhone 14 now has a faster aperture and larger sensor size, essentially making this lens match last year's iPhone 13 Pro. Photos from the iPhone 14 are better, but it may be hard for most people to tell.
It’s the most insignificant upgrade ever devised by Apple… other than the marginal camera improvement, the 14 is essentially a rebranded 13. I see no reason to pick one up and would rather save cash and get the 13 on principle.
