Canonical doesn't want me to use Ubuntu, because they won't allow me to put the launcher where I want, which has been a feature of umpteen different window managers for at least the last 10 years. I don't care that it can autohide. That feature has been around for well over a decade. I care that it isn't where I want it to be, and that they won't give me the option to put it where I want it.
I don't like how I have to click the small window that is not near the top and then go to the top to access the File menu etc.
I don't like that unity doesn't have snap to the right and left side.
