- The trackpad (but other manufacturers now have tolerable alternatives and anyway you can work without it)
- The screen : at an equivalent price point (and even more), nothing comes close to Apple screens. The cheapest MacBook have a better screen than most high end PCs.
- The audio : Apple truly did some sorcery to get such an awesome sound from machines that are flat as sheet. It’s so good that you can watch a movie on your MacBook without earbuds and don’t be bothered.
Everything else like build quality is overall better than most other alternatives but a few other manufacturers are also good at it.
I say this as someone who uses a MacBook for work despite loving Linux and who hates what macOS have become. The hardware is really that good.
To each their own but I really don't want my laptop to imitate that.
