Pihole vs AdGuard Home

Hey, not sure if this is the right community, but looking for some information.

I've seen many people strongly recommend AdGuard Home for network-wide ad-blocking either in isolation, or in direct comparison to Pihole. But I can't really find why there is such a strong recommendation. The only clear reason I've seen is that AdGuard is easier to set-up.

However, I already have Pihole set-up on all of my networks on separate Raspberry Pis at each location. I have it running as the DNS server so that every device that connects to the network automatically gets ad-blocking. I have a few groups set-up within Pihole for slightly nuanced blocking --- i.e. some of my family still want to use Facebook etc. (on a separate subnet).

So my question is, considering I already have Pihole set-up, am I missing some key benefit that AdGuard Home would provide?
