7000 grade Aluminium is a more premium metal than the stainless steel Apple use. It also disperses heat better than stainless.
RAM isn’t an issue for those who aren’t going to use it, it’s there for ProRaw and ProRes etc.
If you are using your phone heavily, then yes that extra ram will come in handy though, I’m not saying it’s not beneficial but only to those that need it/ make use of it.
Build QUALITY is identical. In fact, the regular models don’t have gaps by the earpiece like a lot of the pro models do. So which has inferior build quality again?
You also said it’s an inferior product to the pro and especially the Pro Max… elaborate? As they are identical other than size. Bigger does not equal better.
People can be happy with whatever their choice of new phone, it’s not a competition.
