Hi,
Is anyone able and willing 
to share their experiences ?
Thx & Best.
There should be no relevant difference between the two. Backend configuration is basically the same and filesystem is the same.
So no know issues which are fixed in smb 4.19 or zfs features which are relevant for Macos and samba happiness ?
I do ask because I may update to 13.3 or jump to scale or to somewhere else
What issues are you specifically concerned about? As far as I know there are no outstanding MacOS compatibility issue reports.
