PeerTube Channels?

I am trying to replace my reliance on youtube.

I use GrayJay and have Youtube, DailyMotion(French) and PeerTube set up as sources.

Unfortunately PeerTube has really bad discoverability or little content, I don't know which.

I subscribe to Gardiner Bryant, VKC, TechLore, PrivacyGuides and a few more.

What channels do you recommend?
