> I work with Linux day in and day out for work, and finding my way around Nix, configuring new packages / basic features, etc. just took too long for me.

That was my experience as well.

On top of that, getting something like nVidia's latest drivers working with everything else on Nix seems daunting, so you become fully reliant on the community (which may be lagging behind wrt the newest versions).

I get what you mean, but keep in mind that for every distro you're reliant on the community to get nvidia support integrated. Also if you only have few apps that require it, then the nixGL flake is not bad. https://github.com/guibou/nixGL
