Strongly agree. KDE/plasma continue to make great progress and it's my personal favorite. Looks gorgeous out of the box, is light on memory and the cpu, and offers great customization options. Since it uses a layout similar to Windows 7/10 people coming from the mentioned operating systems feel right at home and it eases the transition to linux (I've installed Kubuntu for a few non-technical people and so far no complaints!). If you're interested in following KDE's progress, check out Nate Graham's blog [0] where he publishes a weekly post going over new features and bug fixes in KDE applications and plasma. Really looking forward to plasma 5.13.
