I’m going to stay away from paid relay recommendations at least for now. Definitely a few I used to recommend that have not been so great lately.

I can confidently recommend #[3]​ as a relay operator. They run the public relays nos.lol and nostr.mom. Public relays have a lot more challenges when it comes to spam and performance but they are a knowledgeable operator that I expect to be around for a long time.
