I’ve used KDE for more than a decade, and then about 1.5 years ago I decided to give Gnome a try. A few months ago I wanted to see KDE again, but I quickly switched back to Gnome.

KDE:

• Feature-rich desktop with feature-rich tools by default. Everything is so advanced and customizable, I really miss this.
• Lately I’ve encountered many annoying bugs (this was the main reason why I tried Gnome in the first place). Crashing while trying to unlock the screen, fractional scaling issues, and random crashes here and there (although these are rare). And I would love to dive into it and fix them, but there are so many other stuffs I wanna do, I don’t have the capacity for this.
• Setting color profiles for monitors is not trivial.
• There are many annoying UX issues that are really negligible, but if they worked well, my experience would’ve been much smoother. Here’s an example: start to type your password on the lock screen, while the monitor is sleeping. On most OS and also on KDE, the first interaction must be to wake up the screen, and then you can type your password. On Gnome, just start typing and hit enter. The screen might wake up halfway while you’re typing, but it still does what you’d expect. These kind of small things make my experience so much smoother and so much more comfortable.

Gnome:

• It just works. Flawlessly and smoothly, to my surprise. Sure, it’s easy to accomplish when it’s so minimalistic, that almost nothing is in there. But whatever there is, at least it works.
• Fractional scaling is a pain in the ass here too, but in a different way. It’s still an experimental feature though, so we could say this feature doesn’t even exist, which is a huge disadvantage.
• Feature-rich software can be installed afterwards. So it’s not really bothering me that the pre-installed tools are too minimalistic.
• Setting color profiles for monitors is very straightforward, but there’s way to improve here too.

To sum up, my preference is less bugs over more features, so I pick Gnome.
