I run unbound at home too.

To me a huge benefit of unbound is that it allows to return whatever you want for wildcards.

Including TLD wildcards.

Seychelles DNS has been hijacked as a whole and only serves malware? Null route the entire .sc.

.ru ? Nah, that won't resolve at my place.

etc.

Then unbound is at ease, even on an old Raspberry Pi, with blocklists made of hundreds of thousands of lines.
