I quite like Chris Were. Very chill, laid-back and nice vibes! There's a nice variety of content: some rambly videos about the fediverse, playing games (including free software ones), and vegan snack reviews. It's on a small instance and the other channels on the instance are good too.

Submedia have some cool political stuff
