Big difference in users and devices here. Tailscale might have a 3 user limit, but you can add up to 100 devices for free. So for me for example I have tailscale running in each and every docker container in my NAS. So each and every container can now act as a node on my tailnet. Users isn't a big deal, any one node can activate funnel with a simple command and poof its available to the public. The convenience coupled with simplicity is what makes Tailscale so god damn good.
Not familiar with either arch or cachyOS, but I'm gonna go and guess that cachy isn't immutable(?) At least to me it's nice to know that neither myself or anyone else can break my system as all system files are read only. Additionally I quite like that I don't have to think about configuring or updating anything - it's all handled by the devs. That might not be for everyone but personally don't want to tinker with my PC that much, I have a server for that 😅
If it's worth anything I daily drive Bazzite but also only game around 20% of the time. It's still a great daily driver, does all I need it to do. Let me know if I can answer any questions.
Yeah staying far and wide away from those ones, thanks
