I agree with you, that the experience a lot of times not as efficient and that its not for laptops. I had some weird problems on 2015 Macbook pro (max config.) where the linux is not able to shutdown the system, and the whole experience requires a lot of experimenting.

Apart from the above points that you mentioned its definitely not getting you the out-fo-box working functionality that windows gives. But i think i am willing to suffer that much to have a system with more control and an OS which doesn't installs random apps without my permission like Windows 10 does[1].
