Apparently the M3's efficiency cores don't get used by Logic Pro so the benchtest has the M2 Max coming out on top. I can't find the video I saw where the guy recommends the M2 Max over the M3 Max but this guy highlights the issue for music production.
Which version of the M3 are you comparing the M2 Max with?
In my experience, M3 Max is significantly faster than M2 Max in every single metric.
M3 Pro is a waste of time.
