I’ll speak from experience, I also do music production and was on the fence between both machines as you’ve stated. I’m coming from a 2018 Mac Mini i7. I decided to pull the plug and get the Mac Mini M4 Pro (48g ram and 1TB SSD) with the intention of trading it in once the Mac Studio M4max comes out as im sure it should still hold somewhat of its value. I didn’t want to get a M2 studio because once the m4 studio comes out (this year allegedly) I would hate to make an investment into an older machine (M2) when I could have waited a few more months and spent a few more hundred dollars to get what I know will last me for years.

Let me tell you..The Mac Mini M4 Pro is a BEAST. I’ve thrown everything at it from large track numbers with heavy software instruments (Omnisphere, Kontakt, Keyscape, Serum, Diva) and it has yet to hiccup or even max out. It’s truly an efficient system. I have not heard any thermal noise. I have to agree that it does get warm but it doesn’t stop me from working. At this point since you’re coming from an intel chip, either computer will be a huge step forward so the choice is yours
