I heard so many of my friends bashing it to hell.
I find it to be pretty good, currently my favorite interface to use on a laptop. You can find plenty of people bashing every DE/shell out there, just use whichever one you like best. Plenty of people use it and like it, but the loud minority would have you think its the worst desktop ever and that no one uses it I hear the same complaints about gnome-shell, but plenty of screenshots of people running that too!
I didn't use it on my old laptop purely due to performance issues, but now that it runs smooth as butter I love using it.
