Ubuntu doesn't suck.
To be fair, that's true of MacOS and Windows too, but Ubuntu makes it easiest to try / think it might be a good idea.
The things they change from Debian are usually things I disapprove of, such as communicating with proprietary services. I think it also tracks user analytics by default, unlike Debian which shows you a modal during installation asking for permission to regularly keep track of your installed packages; and they set the default value to "disabled".
