You know, after you mentioned Time Machine, I thought of another couple (turned out to be a few) of things that I think are awesome in macOS, beside all the obvious stuff.
1 - I really like handoff... I can be looking at something on safari on my iPad or iPhone, or on the iMac and pick it straight up on any other device--I used to e-mail links. I also use handoff on the Mac to answer phone calls, everyone says it sounds great.
2 - Siri on the Mac was somewhat odd to get used to, but I use it a ton, especially for google searches and opening files or apps. Or just to get the weather. You have to use Siri a LOT before it gets really good. I've been using it for years and it gets some of the weirdest words I use correct because over time, she/it learns them.
3. - Touch bar fingerprint ID is spectacular. I have nerve damage from a shoulder injury that makes my right (dominant) hand shake a bit, so the less I have to type the better. Siri on the Mac helps that a lot, too.
4 - Last, but not least, I have tens of thousand of songs, most were copied off of CDs, for the past six years or so, they all came from iTunes. I also haven't bought a blue ray or any movie OTHER than through iTunes and actually (it's ok to do this) share my library with a good friend. I've got over 500 movies and he has about 400. I can download a bunch before go on a trip and watch them on the Macbook or iPad Pro, I've even got a previous generation Apple TV I take along when I'm going to be staying somewhere for a week or so. The best part of all of this, you can stream your content from virtually anywhere since it's all in iCloud or the Apple cloud.
5 - And I know we've mentioned it, reliability. I am 100% positive that there are many times that I don't turn off, or reboot my iMac or Macbook for a month or more. Close the lid on the Macbook and let the iMac just go to sleep--come back and be right where you were. Not to mention it even runs time machine and collects mail in sleep mode.
6 - NO BLOATWARE!!
7 - Spaces--if you don't have Mac, you just don't understand. They're especially cool on multiple monitors.
8 - I know there are other things too I'm just not thinking about.
Take that Windows!!
