NixOS is honestly the single most game-changing thing I've been introduced to in my last decade of experience in tech.
If you're interested in trying out NixOS I highly recommend either running it as an WSL2 VM[1] if you have a Windows machine or deploying it on a cheap VPS[2] to play around with.
I personally still use a Win11 desktop for compat with Adobe software and a few other bits and pieces, but I do all my serious work on a NixOS WSL2 VM.
