I love the idea behind the Pi-hole: block ads at the DNS layer so ads never even reach your devices. No ads, no trackers, and no worries about your extensions breaking! Works network-wide! Unfortunately, it caused me more grief than joy. I love most things…
I use both. I have NextDNS for mobile and PiHole for the local Intranet. A VPN to the home network for DNS did not work well enough for me.
