pihole uses the same method of blocking as adguard dns but is more configurable, and since it's usually self-hosted you have full control over it.

btw, nextdns is pretty good too (think of it as a managed configurable, slightly more private alternative to adguard dns, great if you're not into self hosting).
it lacks custom domain blocklists tho. you can add your own white/blacklisted domains but not whole lists, except ones provided by nextdns.
also, it's a paid service. free tier includes 300k requests per month, which is enough for ~1.5 devices from my experience.
