Did you try all of them?
What made you stick with the one you are currently using?
I became fully aware of Control D only yesterday as the name was vaguely familiar to me when I heard it and for Adguard DNS well I thought it was a normal-ish DNS service like 1 1 1 1, quad9, Google, etc... (not that user configurable).
I tried looking for some reviews and discussions comparing the 3 but found almost nothing about Control D and Adguard DNS but I did stumble upon Control D CEO 2 blog posts comparing Adguard DNS and NextDNS to Control D.
There seems to be not that much talk about these 2 unlike NextDNS which seems way more popular, if I'm correct then what made it way more popular and known?
I've tried all three and I currently use the free ControlD Ads & Tracking DNS resolver and I've been very happy with it. It filters a fair amount of garbage domains in my experience and I don't want to spend time finely tuning the blocklists a DNS resolver uses. I use it over Adguard DNS because I noticed it blocks a few more domains in my observation.
I think most people talk about NextDNS because of the level of customizability it offers, if you want to finely tweak the blocklists and whatnot your resolver uses. It also has a pretty good web interface showing you all kinds of stats and whatnot.
You also have to keep in mind that ControlD is newer in comparison to either NextDNS or Adguard DNS by a few years, so there's likely less people discussing it as it's a little less known.
From what I gathered so far Control D paid plans seem to offer a similar level of customizability but its free offering falls short of NextDNS's free plan, this should be a contributing factor too.
Sounds like chatgpt
Lol
Swing and a miss, bud.
I'll take the L in that case.
