I use Alpine Linux. It's exceptionally stable, great for pretty much any device and is best for small VPS with limited space/ram. Nice package manager too, but it is limited in packages.
It works great for me since I only use docker containers, but some things outside docker may require something like Debian instead.
I'd have left Twitch if I didn't find it more entertaining than current YouTube. No one should be surprised they're at pre-covid profit levels again because they tried to shovel way too many ads down people's throats.
Imagine tuning into a random stream and getting greeted by 3 ads before you can understand if you want to stay or check a different one. I've been frustrated enough that I just turn to something else altogether for entertainment.
There are some decent adblockers like TTV.LOL, which is a simple proxy to a country that doesn't allow ads. But sometimes those solutions don't work either. Ironically I just use Turbo while not paying for YouTube premium, but just as people don't pay for YouTube Premium, I understand not wanting to support Twitch for a variety of reasons.
