Ubuntu, RHEL and Fedora use it as the default and they are very big distros. Idk if it’s enough but that’s what I know.
Hardly, but I’m guessing you’re thinking of reliability instead.
Idk. KDE was unstable for me and it always has bugs after major releases. They should test things better.
Not really surprising when it’s so stripped down that vanilla GNOME is pretty much unusable.
Personal opinion.
That fact makes it especially funny that vanilla GNOME is by far the fattest DE around.
Deepin.
How it manages to use up more resources than KDE is beyond me.
You have a point here. Qt is better in terms of efficiency afaik and performance is extremely important for an OS component. But hey at least it’s getting better over time.
