I didn't run Solaris in production, but at the time it seemed amazing to me. Thumper's management dashboard looked impressive.
I used ZFS and Boot Environment manager a lot on my personal servers, and it seemed to me way better, easier than what I encountered on other platforms.
macOS of course has virtually no first-party management. Windows has PowerShell and its own universe. I have tried to wrap my head around Windows operations for 25 years. I have never been able to internalize it. Maybe Unix-like thinking has ruined me.
