The “problem” is that most people only want an app that does everything, and I’m sure some of my friend don’t want to have two app to do the same thing one app can do.

I prefer to have two perfect app for one task, but not everyone want this.

I need to give a try, I know by name but never use it.

I presume you can make call, good audio and screen share ?

What I meant was that if he wants to try out Gnome, he should install only few extensions to have a vanilla experience. Then he can install the extensions he wants. I would have said the same thing for KDE or any DE.

“Try first without tweak and when it’s work and you like it, try modify” something like this.

I don’t really use KDE, and if I forgot some really crucial information thanks to correct me.
You can use the KDE spin version of Fedora with plasma 6, or if you love the rolling release of Arch you can try openSUSE Tumbleweed with KDE (you choose you desktop environment at installation).

And for what you going to loose if you go to GNOME :

• HDR (you can enable HDR experimental on mutter but not working for me).
• VRR (it’s experimental on GNOME and work for me).
• You need extensions to customize your desktop, its not really a problem but some people don’t want to many extensions (like me).
• Customization in KDE that you don’t find in gnome, even in extensions.
• For Krunner you can use meta button to open gnome overview and start typing to find app.

And if you want to try GNOME try to stay the most “vanilla” possible. Some extensions I use :

• Blur my Shell
• Just Perfection
• Rounded Window Corners (need to do some search for each gnome release to find the new version)
