This can be said about anything. For example, using Linux. Windows has centuries of engineering hours poured into it. It works and is reliable. There's no reason to throw it away and use Linux. If you think Linux is free, wait until you see how much you pay per year in salaries for people whose whole job is to manage this OS. Also, all existing DEs suck in some way or another. KDE is too bloated and slow. XFCE is too minimal. Gnome has countless bugs, and its performance is questionable.
