AdGuard Home is amazing! I used PiHole for a time but did run into small issues quite at lot. Mind you nothing serious but things like these are only really useful if they just work. Adguard Home works without any issues on my Pi setup via docker-compose [1] and it even runs on a second Pi as backup using a cool container called adguardhome-sync [2] to keep their configurations in sync. I am not seeing any ads in my network anymore and it is quite interesting to see how many tracking/ad requests are sent by some devices...
