AdGuard DNS and NextDNS both do the same thing, there’s some differences but they’re pretty much the same (except AdGuard public DNS that doesn’t need configuration). Rethink is the same but doesn’t require an account. Rethink and TrackerControl are also Android apps that give you control over traffic locally. It depends on what you’re trying to do but any of the DNS options (AdGuard, NextDNS, Rethink) will protect multiple devices.
