I could agree with you one year ago. But after latest upgrade to macOS I got so many issues on my MacBook Air and MacBook Pro that I decided 'enough is enough' :)
But then again I rarely install new things, only have a few base programs I run routinely, and reformat regularly.
I've just had a ton of issues with the mouse becoming unresponsive... and then having to do a restart, whereas on El Capitan and Yosemite I could basically leave my computer on for forever.
