I use a few nostr.wine services. They work well, the wino bot is very handy, and they provide excellent customer service. Subscription works well for the filter & inbox. Cellar is time/volume based, which is suitable for that model. I tried some admission based relays. I found the filtering to not be what I wanted. I think that's a byproduct of one-time admission fees. I also use a relay.tools rental. I like the customizable options. Again, amazing customer support. I don't use it nearly to its full capabilities, just as a personal space.
