The good thing of both relays are that they are maintained by experienced relay operators (good system administrator) Mazin and Semisol, so technical problem like server went down is unlikely to happen (reliable relays).
If i'm not mistaken, Wine has 4 regional mirror servers while Eden has 2 regional mirror servers. Wine has extra additional feature (optional extra cost) which is filter.nostr.wine . Eden offer monthly subscription while Wine offer one-time based subscription.
I think you can check on their website to compare and decide based on your needs 🙂
