MacOS does not work as simply as you make it sound.. It requires just as much effort as Windows 10 and MacOS has it's own set of problems just as Windows and Linux does... Linux, once setup properly, is error and trouble free for the most part if you are using an LTS version..
Had you not nuked Windows and if you had did a dual boot, you would have been back up and running in about 5 minutes with Ubuntu removed, the disk space reclaimed and GRUB removed..
Mac OSX works entirely as easy as I make it sound.
And for every issue a new user might have there's easy to understand well documented solutions by Apple awaiting them. All I ever found from Microsoft was various forums with no answers to the problem.
As for the small glitches and bugs on OSX they do exist of course but it's never been too long before they were fixed in my experience.
And I know so many people on the Mac who are idiots in many regards and never need to think twice about the computer. Still boots in seconds. Content well managed. Superficially messy desktop but technically under the hood the OS avoids issues without needing a degree.
