My company uses zoom.us on Win/Mac/Linux. Out of necessity, I also use TeamViewer, NoMachine, and occasionally Skype, Slack, and often just end up phoning them. I can only assume each needs deep integration into the OS because they all have problems. With zoom.us, I've had black screens (when trying to record?), keyboard input problems (where only alpha-numeric characters worked and other characters sent garbage), the mouse would stop working when certain applications got focus, and audio/video problems. These were mostly on Windows--I believe the black screen was on Linux. Screen sharing software also doesn't play well with each other or I imagine other software that messes with audio/video. zoom.us does seem to scale and perform better than the other solutions. I'm not sure it's a great representative of how good the OS is. Apple's keyboards used to be excellent. After the new keyboards came out a few years ago they've been delicate (I've come around on my opinion about how they are to use--but I'm still not a fan of the layout). Replacing them is also a nightmare. So far a keyboard cover has seemed to not have me baby it and prevented a repeat of any issues.
