Setting up Unbound as a recursive, caching resolver is pretty straightforward; a million times more straightforward than doing the same with BIND. You don't need to configure much in a recursor; it just has to accept requests, and recurse until it finds an answer or NXDOMAIN; and then respond.
An authoritative nameserver has a lot more going on; primaries/secondaries, permissions, zone transfers and so on. BIND was the devil to configure, and TBH I have never needed an authoritative nameserver. But I think anyone who can should run their own recursor.

Hah! I reckon it's about 20 years since I touched BIND.
