I use Cinnarch/Antergos three years and I have dilemma to let him go.
When the project is launched it was focused on Cinnamon, and today we have GNOME, KDE, MATE, Openbox and XFCE. This is much more desktop environments than in other linux distribution which have much larger dev teams. Even Arch frankenstein’s distro called Manjaro offer only XFCE and KDE (if we ignore community editions).
I don’t think that Antergos should offer more and more desktop environments if they can’t make it optimized and stable for use.
For example, in XFCE you don’t have even xfce4-whiskermenu-plugin but you have unneeded libreoffice-installer package, you must disable PC beep song, web pages is much worse rendered than on Cinnamon, you have many problems with locking and unlocking screen options and etc.
I do not want to be misunderstood, the Antergos is excellent project but I think it is better to have optimized only Cinnamon and XFCE, than a lot of other lollipop desktop enviroments.
And finally, I would be grateful if devs told us what (distro) and DE they use?
