Blocky can't do recursive DNS either and seems to have a lot less features than PiHole.
And it's a lot harder to configure and use since it is CLI config only and doesn't offer a proper webinterface.
I don't want to have to login to the Pi via SSH every time I want to change some whitelist entry or some other config.
There's zero reason for me to replace the perfectly fine working and easy to use PiHole with something like this.
