I have run my own PiHole previously. Then I wanted Ad blocking on my phone, so I also setup OpenVPN that ran alongside my PiHole so I could get ad blocking anywhere. I travel often, and then we moved, so I never got it set up again, at the same time I discovered AdGuard could be configured on both home networks for network-level blocking, but they also have device profiles for iOS.
I haven’t had to fuss with PiHole now in years.
If you are happy to do the administration of a PiHole, and the scope it provides, it’s good. I didn’t want to have to fuss with it anymore.
