I’d definitely say that USMTGUI and User Profile Central (UPC) from Ehlertech is currently the most comprehensive User profile handling tools out there.

Ehlertech is maintaining USMT and updating on a regular basis.
Something Microsoft has not done for years.

UPCs advantage over USMTGUI is that UPC handles domain profiles remotely over LAN.
USMTGUI on the other hand is capable of migrating to AAD accounts.

If you have any custom xml files in your SCCM setup you can also integrate those with UPC

@xavierdelaraunt said in User Profile handling anno 2022:

I have quite a lot of settings I cannot get into the default settings in any way like that.

I have not ran into any policies, settings, etc that could not be don't through Intune. It would be very hard for me to think of something that I can't do to a device related to those through Intune.

If you are referring to user profile migrations across different devices (old device > new device), most of that can be resolved by better systemic practices prior. That can be a shitty experience regardless of MDM or device management system.
