From a sysadmin in the field - it's complicated.

New Server features are primarily controllable via PowerShell and now only secondarily expose a bit of control via GUI. So, indeed PowerShell has taken precedence. However, it would be wrong to say that Windows administration is exactly like managing Unix systems. On the contrary, the more one works with it the more one realizes PowerShell is the anti-Bash.

Lacking in the aeons of interface legacy built into standard Unices, you won't find standbys like 'grep' readily available or even easily implemented. Rather, PowerShell is built from the ground up for scripting. While the addition of SSH will certainly be helpful for quickly checking statuses, (and possibly more in the future should readline usability of PowerShell improve) right now most PowerShell interactions happen via scripting from a local workstation or web or application inputs rather than directly via the interactive shell.
