In the free ones purplepag.es doesn’t actually relay notes. But it does make your nostr experience better.

I also use the damus one and snort social one (lots of users on each one of those)

Another thing about nostr.wine. They also have welcome.nostr.wine (free) which only relays info from new npubs. So it’s really useful to find new users. On global, i only use the filter.nostr.wine and welcome.nostr.wine
