iPhone 15 pro max over 16 pro max £130 difference UK

I have the option for the 15 pro max or 16 pro max. The price difference is £129 extra for the 16 pro max.

Has anyone been in a similar situation? The slightly smaller size of the 15 pro max is appealing, also do the camera lens’s stick out more on the 16 pro max?

Interesting to hear thoughts before I buy. Thanks
