Ditto here. NewPipe + VPN works fine on my tablet I use as a YouTube machine. The only problems have been when YT messes with stuff to try to block them, and then NewPipe will have it fixed usually within a day. And that doesn’t happen as often as people think.
I used Sabayon for a bit too. It was basically “Gentoo made easy” with a simpler installer and as you said a binarypackage manager rather than compiling packages from source. It’s wasn’t 100% completely dead after dropping the Sabayon branding, it morphed into Mocaccino Linux, but when they did so they re-based it on Funtoo, which is also now dead.
