iPhone 14 or iPhone 14 Pro Max?

Hello folks,

I recently received a 128GB iPhone 14 through a contract extension. I've been using it for two weeks.

I'm actually happy with the phone, but I would have preferred the Max.

Now my question:

I saw an iPhone 14 Pro Max 128GB on eBay classifieds with no defects or signs of wear. It would cost me €650. It has 92% battery capacity.

Someone wants to buy the iPhone 14 for €550. It still has a one-year warranty.

Is it worth it for me if I get it for 650€ and sell mine?

what do you say?
