No - if there was a "best relay" that implies that most users would want to join this relay. Nostr is - in theory - censorship resistant, because there's no "best relay".
Discussion
“Best” is defined differently by users which is why having more information about individual relays is useful. There will always be bigger relays that users gravitate too, even with a successful gossip model.
It’s censorship resistant because the data is replicated, portable, openly accessible, and self signed.
So wouldn't you agree, that it would better, if users don't have to pick a relay? Because if properly implemented (protocol), it shouldn't make a difference?
What you're describing sounds like a Matrix / Mastodon problem.
In fact, if you give users the choice, it does exactly what you're describing
> bigger relays that users gravitate
Isn't that the opposite, of what we're trying to achieve?
