Immich has completely replaced Google Photos for me, love it!

My only bugbear is that it is updated very frequently (what a nice problem to have!) which in my case requires a manual once-over of my docker-compose file every time in case there are breaking changes.

I use both. Pi-hole running in a docker container on one of my home servers which my gateway is configured to assign as the default DNS for all clients, and uBlock Origin on all my browsers to catch everything else.

Pihole is pretty good at catching ads on platforms that are not suited to browser based blockers (IoT devices, streaming boxes etc) but it isn’t perfect and is best used in conjunction with another solution.
