I started using powershell more because it comes with a lot of bash aliases out of the box. Besides a brief period of using ubuntu in like 2006 because my windows install got corrupted, its my first foray into linux. Ive been daily driving debian 12 and i love it. I feel like getting used to the lingo helped ease the transition.
But if you actually use powershell for more than simple tasks and take advantage of its object oriented nature, it might make the switch harder. If you plan to use the command line as little as possible i think the switch is trivial. Your biggest worry is going to be analysis paralysis with all the options, but i just installed debian with the defaults and trying out different desktop environments is really easy and i havent yet had a problem that wasnt simple to solve with a google search.
