For me it just brings a lot of peace of mind to be able to click on any link and not have it blocked by ublock or pihole.
All links are what Kagi believes to be valid results.

Cannot judge on the quality filtering tho.
I'm a happy user of NextDNS rather than a PiHole, but the rationale is the same: use DNS blocking to block stuff that you never want anything on your network to see, and use uBlock Origin for fine-grained blocking of the rest.
I wouldn't want to rely exclusively on DNS blocking, because it won't block at the right level of granularity. I wouldn't want to rely exclusively on uBlock Origin either, because it doesn't work everywhere I want to block stuff.
The only downside is email unsubscribe links. Those annoyingly tend to be on domains blocked by the various block lists NextDNS uses.
