brew install coreutils

Getting GNU tools on MacOS is super easy and honestly I don't know anyone using ports/fink. All of my development ends up on Linux machines, in rare cases I need something specific to Linux or my production environment, I just connect to a dev machine but for the most part I use MacOS as the primary desktop at work along with everyone else.

For me it's all about workflow. I spend a lot of time in alacritty, vscode, and a browser with bitwarden. I'm covered on every OS with those tools so I've stopped caring about OS all together, I like bits of all of them, and dislike bits of all of them.
