But I think this is the point. PowerShell (or the spirit of it) would be more useful for new users because they don't need to spend time memorizing every single command and can start being productive earlier. It probably makes less of a difference if the commands are already part of your muscle memory.
Though to be fair, CMD is a lot more quirky and inconsistent than modern bash. So before the advent of PowerShell, I think you could have made the same argument on favor of ...nix and against windows.
