I think techtinium is a self hosted solution if I’m not mistaken? Not really heard much of it so if it fits your needs then great. I like nextdns because I don’t want to self host my private dns and it is easy to setup and monitor for all my devices and provides a lot of lists to easily choose what I want to block on what devices. For example I have a different profile for my kids with parental control. Medium for the wife so that her internet browsing isnt distupted and strict tracker blocking for myself because I don’t mind things not working.
