Is the hardware so much better, or is their integration superior? macOS can be bloated but still more efficient, right?
I mean, the "so much better" in my experience is really the battery life.
The Intel period of MacBooks allowed a more direct comparison. Don't think macOS itself is the differentiator vs Windows.
But vs Linux, well even Linux on a non-Apple laptop tends to mean screwed up power management. The display system might be less efficient too, depending whether it's X11 or Wayland, and idk which one is the good one.
I will deal with everything I dislike about MacOS for laptops that never cook my lap and never, ever, ever randomly turn on full power while in my bag
That is my exact take - new Mac Book Pro M5. Love the battery, like the hardware quality, don't care at all for the rest of it. MacOS is annoying.
their single core perf is just much better than anyone else
They are the only laptop company who makes a fanless laptop that never gets hot to touch with long batery life. I'm still on my m1 air with the smallest configuration you could get at the time. Yet it's somehow capable of matching my T14 i7 with 32gb og ram for most of the work I do, and it does it without getting hot or having it's fan sound like it's a fighter jet taking off. To be fair my t14 is a corporate windows machine, so it's not like it's a fair fight.
I'd love to replace it with something like a framework or a tuxedo, but they all get hot to touch. Maybe I'm in the minority, but a laptop not heating up when you turn it on is one of the most important things for it. It doesn't matter much for work, because it'll sit in a dock anyway, but I rarely use my m1 air at a table.
