I've been using KDE for a good decade or so, and what a lot of people don't know is that not only is the desktop great, the applications are, too.
Everyone knows Dolphin is by far the best file manager, but not a lot of people know that Kate is fantastic. Konsole is really good too. The new System Monitor basically replaces a ton of programs. Spectacle is a great and snappy screenshot utility. Filelight is so useful.
There's definitely a few misses, though. kmail in particular. But, overtime the applications actually improve, both in performance and features. This seems to be in contrast in gnome, where apps like Nautilus have been getting worse for a long time. And in contrast to Windows.
System monitor can do all this stuff, pstree and all, and you can get really cool visualizations. Pi charts, line graphs, and my personal favorite, color grid. That one's really good for CPU utilization.
But the real icing is that it doesn't just work for processes, applications, CPU usage and whatnot. It works for any sensor, including temperature and fans. And, of course, it's all customizable.
Be that as it may, it is slow to start, or switch between different views. I tested that again just now. Furthermore, it's causing more load by running, than one btop++ or htop running in Konsole. Which btw. both show temperatures, and could also show the rpm of the little 'Miefquirl'...err.. fan if I wanted them to.
That's seems to be common for all the monitoring stuff running graphically, no matter if Gnome, XFCE, or even old KDE (Trinity).
That aside, htop and especially btop++ are heavily customizable, too.
Whatever. To each his own. It's a matter of taste.
Yeah it's pretty fast but it's still a full graphical application. It's probably written using QtQuick so it's fast... ish. Terminal applications are almost always going to be much faster. But, it's a neat application that doesn't get much competition on the GUI side.
