It's uneven in my experience. OS-wise (Android, ChromeOS), I've had some big and frustrating problems. On the other hand, I really like some of their web apps (Drive, Docs).
For servers, yes, but use Safari for like 5 minutes versus Chrome and it’s clear the reverse is true for desktops, especially if you’re not running with 32+GB of RAM. Google Drive, Photos, etc. are not as good as Chrome.
This is not to say that Apple’s desktop software is great, only that the bar is a lot lower than it had to be when people had to be convinced to buy licenses.
Ah yes, the company that still can't their gesture and backswipe UX functioning properly 7 years after its introduction, and with Apple giving them 2 years to study it beforehand.
A decade to produce a non-functioning gesture bar / system. Such a titan among titans.
Usability wise (UI/UX/design), they are in the gutter.
