Stable, in this context, just means "point release". If you meant "doesn't break", that describes most rolling release distros.
...unless you've used KDE in the last month. Holy cow, just let me alt-tab into a fullscreen window without throwing a fit.
I don't hate flatpaks, but flatpaks require more disk space than the same apps from traditional repositories, and they only support a handful of the most common default themes. Since I only ever use older and slower computers, my disk space is limited, and I like to rice my desktop, I personally avoid them. But your use-case may differ.
I played with Endeavor years ago, but not extensively. If memory serves, it's pretty much just preconfigured Arch with some nice theming, a Calamares installer, and a few simple scripts. Garuda adds even more theming (too much for my tastes, actually), a few GUI utilities, notifications when your system is overdue for an update, and an update script that runs common post-update tasks (like grub-install) and takes snapper snapshots automatically, so basically user-friendly bloat.
Disclaimer: I'm incredibly ignorant. Wouldn't wireless necessarily mean high-latency?
If you like arch but want a plug'n play distro, just do a plug'n play arch-based distro. Garuda is braindead easy.
It does not run well. You can't see the performance difference between KDE and XFCE on neofetch, but you absolutely can on on old machine.

Enable the chaotic AUR and you won't even have to build from source.
Linux is modular, not fragmented.
Except Gnome. Fuck Gnome.
Wait, are you setting up PPAs? If you're using a user-friendly distro, either flathub should be enabled by default or the AUR is easily accessible with pamac or the chaotic-AUR. If software availability is a problem, I don't know what to tell you; I think you started with a more difficult distribution than you intended to. PPAs suck.
Thank you for providing an actual answer. Most of the comments in this thread are condescending as hell.
People think Biden may actually do it? I hope I'm wrong, but I think that's pure fantasy. One ego is definitely bigger than the other, but you don't become President by being a good person.
