On Windows 10, the most comprehensive SKU is Enterprise. It contains every feature unlocked and enabled by default. Very much like the Ultimate SKU in Windows Vista and 7. But, is that still the case on W11? Microsoft promotes W11 ProWS as their "most powerful OS yet".
The best version IMHO is Education. It has all the features and all the rules in Group Policy Editor work such as disabling Telemery (diagnostics data), Cortana disabled by default, with none of the extra things that Enterprise offers which you would never use

Enterprise does include the Ultimate Performance power scheme like Pro WS. I came to the conclusion that Enterprise really is, literally "Windows 10/11 Ultimate".
Enterprise basically is Education and Pro for Workstations combined, and akin to Windows Vista Ultimate combining features of Home Premium and Business. I speculate that Microsoft mentions Pro for Workstations as their most powerful OS because it's the highest (and most expensive) edition available for direct retail purchase. While both Enterprise and Pro for Workstations feature Group Policy Editor, some policies are applicable only on Enterprise and Education editions. If you can get Enterprise and you'd like Spotlight to be disabled just like in editions "Pro Education" and "Education", you can do so via GPEDIT. Here's how: User Configuration -> Windows Components -> Cloud Content -> Turn off all Windows spotlight features --> Enable.
Resilient File System (ReFS) I've done performance comparison tests between Windows Pro (WP) and Windows Pro for Workstations (WPW} in Windows 10. What I found was that file transfers were faster in WP than with WPW. Graphics performance was faster in WPW than with WP. The lag in file transfer performance may have been due to implementation of the Resilient File System (ReFS). ReFS may perform extra file system functions that may make it more reliable, but slow it down. I eventually settled on WP because I wanted better file transfer performance. I did these tests a couple of years ago, and I apologize for not having an actual report of these results.
Sorry, but I cannot remember. But it would have been in 2021. Many websites are claiming that performance should improve with ReFS. But I did not find that to be the case with my Dell Precision workstations. It may have been a hardware issue. But since I tested, I stayed with NTFS instead of ReFS.
