I use both. The friction is way lower on the Linux side of things. Sure you can knock up a 50 line powershell script to thing X but if you do it in 97 lines of python it takes less time because you didn't have to download a later version of management tooling which then required a reboot followed by half an hour arguing with script signing followed by an hour of trying to scan through KB articles to work out why your PS script didn't run in task scheduler only to find it was an obscure compatibility flag followed by it failing after two days because a CIFS share suddenly went offline...

And today visual studio 2013 crashed on me a relatively low 11 times...

Oh and I had to fix a script that tried to deploy sql server instances and pretty much entirely fucked up my workstation.

This is every day when your product gets large.
