I've just migrated from a 4 year old Macbook to top of the line M3 Max. My previous Macbook had multiple kernel extensions, lots of customisation and homebrew apps and such. I was convinced that I'd spend a significant amount of time setting it up again - so I'd made some bash scripts in preperation to reinstall my homebrew stuff etc.
So upon receiving my macbook I used the migration assistant and ticked everything, and to my surprised I've spent less than an hour getting this new machine up to speed. It moved everything including all my settings, apps, configurations for those apps etc. The only issues I've had is docker didn't move across, and I've had to manually download universal binaries of a few intel apps. It has been completely flawless.
I don't see the value add for the use-case you describe of machine migrations when Apple's tool for this works so well.
