Happy nextdns user here who used to have an overly-complicated setup with pihole and vpns etc. The only thing I have to complain about is the iOS app- I really wish it had a builtin way for viewing logs and white/blacklisting domains from the app, without having to go to the site. (Other settings would be nice too, sure, but as aggressive as I run it I find myself fiddling with the whitelist the most)
