Been running a pi-hole with unbound for years here. Apart from updating the roots file every six months its been sitting there doing it’s thing happily without skipping a beat. I did take a small look at Adguard but couldn’t see anything like the tail pihole log option which I tend to have in a tab as I like to see what’s going on.
A lifetime of being allowed to do what they want, when they want and not worry ;) ??
At the worst a week under house arrest .
