I came to a similar conclusion. I love tinkering and messing with stuff. Those in my household also enjoy (tolerate) my tinkering. What they don't enjoy is when that tinkering impacts them and is unreliable. The amount of time I spent on a monthly basis keeping PiHole working (through updates, list updates, and the random "PiHole just stopped resolving all requests" was laid bare when I paid $19… and didn't ever have to touch it again. The bonus is that I can access it on every device I own, anywhere in the world. I appreciate PiHole and I know there are use-cases for it; I just couldn't go back after trying NextDNS.
