Mac Studio or the new Mac mini?

I just traded in my Mac Studio M1 in for the new Mac Mini M4 pro.. The performance appears to match (and exceed in some areas). I wanted to future proof my Mac and try using using the TB5 ports when hardware becomes more available. Also takes up a lot less desk space. There is one YouTube video that runs a comparison between the units and it backs up what I discovered as well.

Intel Macs starting with retina models introduced in late 2012, the RAM was soldered to the board for maximum reliability. No model after that has modifiable RAM.

a few years later, the SSD components were also soldered in place. Starting about 2017 models, these have NOT been commodity SSD drives, so even if they had been in a slot, they would NOT be replaceable.

With Apple-silicon Macs, the supplied High Bandwidth Memory is on the same chip-carrier as the Processor for maximum SPEED as well as reliability. Designing it otherwise means you can't get the desired speed, because sockets/slots, and "off board" design rules preclude fastest access.

The amazing performance of these systems on a chip comes at a cost of no user upgradeability.

Buy what you need now, especially for RAM memory, because the only way to UPGRADE is to sell the computer you have and buy a computer that better meets your needs. But since computers are a commodity (a particular model is just like every other sample of that model, they have no ART value) that is not such an outrageous way to proceed.

For photography edit work, the new Mac mini will be awesome

Whichever you choose, be sure to buy a model with enough RAM. You can't add any more later.
