Can I ask what do you dislike about both NixOS and Arch, since you've been switching between them?
I thinking about trying out nixos but I'm afraid it:s too much of a hassle
Windows (for my entire life) -> Ubuntu (for half a year) -> Kali (for a year; yes, I was that kid) -> Manjaro (half a year) -> Windows (for a short while, my Manjaro broke and I had school) ->Arch (past 4 years) -> now trying out NixOS
Recently I added a custom domain to my protonmail account and during the procedure it makes you do this steps (adding SPD, DKIM and DMARC) to pass all the steps. They tell you exactly what records you have to add, where to add them and what the content should be. These guys are great
You would want to setup a VPN server on your linux server and vpn clients on android and laptop. I'm not knowledgeable enough to help, but you can look into wireguard
I understand pirating from Netflix and such, cause they're big companies and their service is shit, but Nebula is run by creators and you support them directly with a subscription. So if you have $5 at your disposal I would highly encourage paying for Nebula.
