Usenet is generally better for 0-day and recent releases, but it doesn’t hold a candle to P2P when it comes to older stuff. What’s the max retention you get with the most premium plan with reputable providers these days? I think it was 13 years last time I checked. But aside from that, it’s almost always faster than P2P (unless you have a bad connection to the server from your location) and certainly more convenient in certain categories like movies and TV shows. I still use P2P for games, software, and music though.

Edit: Forgot we were talking primarily about security. Of course Usenet is better in that regard as well. The other replies explain why that’s the case.

Did you mean to say Dolby Vision?

Soulseek, among others. Putting my ~400 GB classical music collection out there.
