No insult intended. I genuinely wasn't aware of what advantages macOS offers for a power user (by which I mean someone who wants to do tasks more advanced than browsing, email, etc.). From quickly skimming the replies the common theme seems to be a mixture of battery efficiency, hardware compatibility, and Mac-only software.
> Been there done that. I have too many other things that need to get done to build up a distro.
Yes, but my comment wasn't made in isolation or directed at people with your objectives. The OP's article is about doing exactly this, but in the opposite direction (expending large amounts of effort to remove unneeded processes). See for example: "if we assume that we need to identify just 500 candidates, and each takes an average of one week to research, that would take over 10 person-years".
Starting with that as the baseline (as opposed to starting from your position which is that you're not interested in spending time on this issue), building up from zero is a lot more straightforward. And, if you use something like NixOS, you generally only have to do it once since the idea of "reinstalling" the OS (e.g. for new versions) largely goes away: subsequent effort is just about changing your mind about what software you want, or what version you want (as with any OS).

It's been out for a while.. why are you interested in the debate if you've come this far, have no idea, but want to lead with a counter-assertion?
> what advantages macOS offers for a power user
The serious answer is that you get an "it-just-works"⁺ Unix-like operating system that gives you a development experience on-par with Linux.
If you are doing sysadmin stuff: you will not like macOS.
If you care about configuration for your window manager, desktop environment, or systemd services: you will not like macOS.
If you are a graphics engineer or a kernel engineer: you will (probably) not like macOS.
If you are a C++/Rust/Python/JavaScript/Java/mobile/desktop engineer who wants a rock-solid developer environment and doesn't care about the above: you will like macOS.
You get all the Unix tools you could ever want, whatever shell you want to use (Zsh, Fish, even PowerShell), clang/LLVM, etc.
Does that answer your question?
⁺: caveat being "it just works" is getting less and less true with every macOS release.
