I'm not a huge fan of those DNS ad blockers. Sure, they block everything on network-level, before requests get to device, but this method is becoming less and less efficient every single day. If you look at the filters and whitelists of these ad blocking DNS servers, you'll see that whitelists constantly grow more and more. This is done because DNS doesn't really have any mechanism by which they could whitelist just specific requests and instead they have to whitelist entire domain for all websites in case of any issues. This is especially visible on websites that serve ads from their own domain, so basically, they only have two choices; either block entire website or whitelist entire website. There were also a lot of cases of website breakage which take time to get fixed as entire process of filter updating is manual.
This is why I only recommend using DNS ad blockers on devices which either have ad blocking app or extension in the browser. If website isn't working because it's blocked by DNS ad blocker, app and/or browser extension will fix the website for you using cosmetic filtering. DNS ad blockers should be used complementary with other more efficient ad blocking solution and then you'll get total protection. This is how I use AdGuard DNS, along with uBlock Origin in Brave and on Android, with their own app. Never had any issues or ads left on the websites.
