Mac Mini M2 or Studio M1 Max

Hi,

I currently have a 27' iMac, 3.5Ghz, quad core Intel Core i5, 16GB RAM, 2400Mz, DDR4. I'd prefer to buy another iMac but need the bigger screen that they no longer do.

So, I'm looking at either an Mac mini or Studio which I will team up with an external 27" screen (sadly not the Apple one as it's horrendously expensive!

I can get a Mac mini M2 10-core CPU, 16-Core GPU, 16GB RAM, 512GB or the Mac Studio M1 10-Core CPU, 24-Core GPU, 32GB RAM, 512 GB models for pretty much the same price at the moment due to a good deal on the latter. The question is which is better?

I use the computer mainly for running my business, updating the website and manipulating photos for it.

Any advice on this and what 27" screen to match with it would be very much appreciated.
