Extremely. I've tried KDE flavors of various distros and one thing that trips me up every single time is the workflow for connecting to my hidden WiFi network. On Gnome and Cinnamon I can do this in a few clicks from the network icon in the task bar. On KDE I always have to spend several minutes fumbling my way around the network settings before I can start using it. Every. Single. Time. I don't know why, it's like my brain just works a certain way and because this is such an early and crucial step in setting up a fresh install, I've never been able to stick w/ KDE despite all the rave reviews it receives in these types of posts.
