I started using Xfce years ago because I had a very cheap and weak laptop, for which even Cinnamon was too heavy. LXDE worked a bit better, but at that time it was too ugly for me and I preferred a bit heavier Xfce (although I must admit that LXQt in Lubuntu 20.04 properly configured does not look so bad – my girlfriend uses it on a weak netbook). I used Xfce first on Xubuntu and then on Linux Mint.
Later, when I bought myself a laptop with a decent specification (i5-8250U, 8GB of RAM, SSD), I was so happy to finally be able to use heavier DEs, that were previously out of my reach. I've been testing different distributions with GNOME 3 for several months, but unfortunately, although I like some great solutions, this DE has too many weird bugs, that spoil the whole experience in random moments. Cinnamon works great, but I rejected it for some reasons. KDE, although really lightweight these days, is poorly designed – the typography is awful, the different elements do not fit together, as if they were created by teams of programmers who cannot communicate with each other. Besides, whatever you click, a ridiculous number of settings appear. I respect the work of team behind KDE, especially since it is a very popular choice among Linux users, but for me it is too messy.
So even though every distro and every DE will work on my current laptop, I went back to Xfce (Manjaro Xfce, to be specific). It turned out that I fell in love with how light, simple and stable the Xfce is, so much that I prefer them to more fancy DEs. Xfce is great if you just want to start the computer and get things done.
Of course, there are things I miss in Xfce. For example, hot corners from Cinnamon. Or a beautiful and useful music applet from Cinnamon, featuring a large album or podcast cover. I also miss the view that shows up in GNOME 3 when you press the super key, with thumbnails of all the windows opened in this workspace. But overall, I absolutely love Xfce. In GNOME, the first bugs that froze my windows occurred an hour or two after installing Ubuntu 20.04, forcing me to reboot. In years of using Xfce, it hasn't even happened to me once.
So, what's your story with Xfce? Have you tried that DE? Did you like it? And if so, please write if you configure it at all? You add some non-default applets or themes? What do you miss about it?
