I currently have a M2 Pro Mini, and will most likely get the M3 Max Studio.
If course, it depends on when it launches, what the specs of it when it launches, and the launch price of the M3 Max Studio.
At one point, I was thinking about getting a AS Mac Pro, as my Mac Pro 1,1, while still daily used, is a power hungry, aging beast that needs to be retired.
But everything I liked about my Mac Pro 1,1 and what has kept it going on for many years, the AS Mac Pro doesn't do or doesn't do as well, upgradable GPUs, RAM, and easy internal storage options. The AS Mac Pro was pretty disappointing to me.
The Studio is a much better deal, given the issues mention above.
Currently have a M1 mini. Working great. Wanted the studio but decided to wait.
I have a M1 Mini as well, and was going to wait for the M2 Max Studios, but the M2 Pro Minis launched, and it seemed like a pretty good deal at the time, especially since I had no idea when (or if) the M2 Max was going to launch.
It retrospect, I wished I would have waited a few more months for the Studio, but a the time, the M2 Pro Mini seemed like the logical upgrade to my underpowered M1 Mini.
Happy with the M2 Pro Mini, but will probably get the M3 Studio when it launches.
