Granted, most folks will be just fine with just those 2 enabled, but I chose AdGuard since they supported all the Hagezi lists short of his Social Network blocking list. You can add Hagezi’s other lists to Control D using their folder function, but AFAIK those lists don’t automatically refresh and they take some user tinkering to get set up. I do give credit to Control D for offering a number of free DNS servers - including ones for Hagezi Pro, Ultimate, etc.
