From my point of view, it's mostly about reliability. You can use the hoster's DNS resolver, but be aware that a high-bandwidth exit asks a lot of DNS requests. Not every hoster's DNS resolver might be able to cope with it and as a result your exit might give users a poor experience.

I was setting up exit nodes and I had a question. Why is it recommended
to use DNS caching software Unbound? What benefits does it provide
compared to using hoster's DNS resolver?
