The big problem with DNS-based ad-blocking is that it doesn’t prevent redirects. Sure, you’ll get redirected to a harmless blank page, but then you need to go back to the previous page. You don’t have that issue with uBlock.
It also doesn’t prevent advertisements carried through the website’s own domain. For example, lots of video platforms send their advertisements through the same domain as the content’s domain, so if you block that domain, you’ll also block the possibility of watching any content there. That’s why you need to have ad-blocking within the browser.

Also doesn’t do cosmetic filtering - like, it would remove the ad, but not the HTML box that used to contain it.
Yes, that happens when I click affiliate links. Blank page and then I go back.
