Manjaro, a stable descendant of Arch Linux. It has stable updates every week (more or less). You can select your favorite DE, kernel version, it is updated for optimal gaming performance, easy to install like Ubuntu. If you miss any app in the Manjaro repos you can always download it from **AUR **(Arch Community Repo), **Flatpak **or **Snap **by activating it easily from their app store.
Yes, it is similar to Endeavor OS, but I think Endeavor is more like an easier version of Arch, but just as edgy with updates and the instability that comes with it.
