I would beg to differ. From an exposure perspective they are identical. They both ask questions onto the network and both have to parse and process those answers.  They both produce similar CVSS scores, which are a much more objective way of analysis the need to pay attention to a security issues.  BIND and UNBOUND both have had CVSS scores of 7.5
for packets of death.

A packet of death that does nothing else has a CVS 3.0 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

CVSS, v3.0, a score of 0.0 receives a "None" rating; a 0.1-3.9 score gets a "Low" severity rating; a score of 4.0-6.9 is a "Medium" rating; score of 7.0-8.9 is a "High" rating; and a score of 9.0 - 10.0 is a "Critical" rating.

If it the fault leads to a potential remote compromise you get into the Critical range.
