Yeah I really enjoyed Cachy but the model of using the AUR to install third party applications just seems broken. I don't want to have to trust some random install script maintainer in addition to the 3p app developer. And sadly I don't have the time and attention to spare to review the AUR scripts of apps every time I update.
I switched to Kubuntu to keep KDE (which I really found I enjoyed from Cachy) while using a more stable and familiar ubuntu base. It's not one of the "gaming" distros but I haven't noticed any major drawbacks with the games I play.
