AOSP with MicroG vs Nextdns with good lists

How better is AOSP or Graphene OS with MicroG or Sandboxed google services compared to just using NextDNS with some good filters.
I mean microg or graphene os will still connect to internet for google stuff I use. Also I can block internet access for a domain using NextDNS which is quite similiar to cutting network access in graphene OS. So how come stock android with NextDNS is less private than MicroG/GrapheneOS.

    Honestly I’m not technically knowledgeable enough to answer, you can have a read of their FAQs. But my understanding is that the sandbox allows some google services to be used, but without privileged access to the rest of the system. As opposed to blocking them entirely, which would mean you couldn’t use those services at all. https://grapheneos.org/usage#sandboxed-google-play
