I know this has been debated for years. But I wonder what you mean. As I say, the build quality on any Apple product is second to none. MacOS and iOS are tuned precisely for the machines they run on, and they show it, running incredibly efficiently. iOS especially does the whomp-whomp on Android, but that's an issue for another dayt.
Macs will run FinalCut and Logic without breaking a sweat. In the real world, they run efficiently, low power, and will last a long time. This is a great solution for many people who will get everything out of a Mac. To run a Mac yourself without being an IT tech is easier, usually, than using Windows PCs. Usually.
Windows 10 is pretty solid. I've had blue screens from drivers, but as a heavy user (and someone responsible for testing/endpoint managing models of laptops, both Mac and Windows), it's a push. Doing something particularly technical on a Mac has resulted in plenty of kernel panics.
As a Mac user, yes, there have been plenty of times when I would have said that, pound-for-pound, MacOS is "better" than Windows. However, Windows is a lot more stable than ever, has tasteful aesthetic defaults for the first time, has Exposé and multiple desktops finally, integrated GNU/Linux if you need it, and it will run a bunch of boutique software and games which still get put out only for Windows. Whereas on MacOS in the last few years, I've found it incredibly annoying fighting with Keychain in a managed environment, and the rollout for the new file system caused a lot of problems where people I knew who managed their own Macs still were reduced to reinstalling or recovering their entire OS.
The Windows 10 UI is still garbage.
Windows 10 Explorer is garbage. It doesn’t even have Recent Places. I have to manually browse the file system a million times to places I’ve been a dozen times when I open and save in Windows. Z: drive, clients, B clients, project H, logo.psd. Go to Illustrator and select open, again click Z:, clients, B clients, project H...It’s a joke. OS X has a recent places pop-up in all open/save dialogues and in the Finder. And the open/save knows where you were in the Finder. Windows? The Quick Access only shows you “frequent places”. That right there makes OS X 10X more productive. It’s insane how much time I waste navigating the file management.
The old Windows open/save dialogue from the 1990s still shows up. Example, “save optimized” on the latest Photoshop! It’s the 90s!
Print que comes up on OS X then goes away when the printer is done. Windows? Nope. You gotta go hunting and manually bring it up and leave it if you want to see the progress of future print jobs.
Taskbar is garbage. You click on Word and it shows you a thumb of every document you have open versus just going to Word and bringing up the document I’ve been working on, like the Mac. So two clicks every time. Hacked the registry to get close to OS X . Can’t launch documents by dragging and dropping on app in Taskbar. Gotta right click and say Open With.
Finder rename of multiple files is superior to Explorer. Very handy and powerful.
Copy files in the Finder on OS X and if there is already a file there with the same name, it asks if you want to overwrite or copy as a different file with a different name. Brilliant! Windows? Nope. You can overwrite or cancel.
No Quick Look in Windows. There is a utility called Seer. That adds it, but doesn’t support as many file formats, like Office. I use it all the time, especially in the open dialogue.
Windows 10 doesn’t wake up from sleep as reliably, doesn’t wake up dual monitors as reliably.
I have to restart Windows 10 on my work Dell laptop way more than I restart OS X (months go by).
I never had to reinstall OS X.
Integration with iphone with Airdrop is wonderful.
Text messages on my Mac through my phone with a keyboard with iMessage is wonderful.
Column View is better and more productive than the side bar in Explorer.
Coupled with tabs in the Finder, I’m way more productive.
Settings and Control Panels in Windows are still a mess buried under properties, under advanced properties. OS X system preferences is a superior UI.
Start Menu with the panel squares is idiotic. I had to right click on every single one of them and unpin manually.
Outlook on Windows has a UI from the Soviet Union. OMG! A million little icons and tabs that are horribly designed and inconsistent. It’s just hilarious that reply and new email are on a different tab from get new mail. I spent so much time trying to fix that mess customizing a ribbon.
Microsoft has no idea what they are doing with user interfaces. To this day. It’s embarassing.
