Linux

Also, if we're gonna be talking about which CLI is easier to learn and use?

I wonder if its Linux, which has different programs for each flavor (apt get vs pacman vs yum) and whose command-set is from the 1990s where you had to use as little code as possible because of space/cpu limitations so the names for what each command does are not very descriptive...

Or is is Microsofts Powershell which has an extensive get-help command which provides a deep-dive on each and every command there is on top of all the commands being human readable in a verb-noun format that can be read by a layman and generally understood what the command is doing simply by its name. Oh and get-command so if you're not sure what command you need, you can search for it by keyword.

Man pages can be pretty useless if you don't already know which command you need. In Linux you don't have as many options of learning what the command you need is, because they're not human readable. Instead you have to search online and hope someone can clue you in to the right command/set of commands.

Linux is the better OS, but Microsoft made the right choice by making Powershell commands human readable and straight forward. If Linux was being started from scratch, this is something I would put in the pipeline: "Human readable commands in a verb-noun structure."
