Which is more powerful/useful?: Cop or Doctor

[Tierce]

Duh. Cop of course.

Those of you who actually voted doctor -- could you explain why?

You realize you are asking this question of people who posted in a

2005

thread, right? And that

nine years ago

, Cop sanities were used much more often and resulted in an overall higher value of Doctor over Cop due to Cops being unreliable?

Because nowadays the answer is (still) obvious, but trying to get explanations out of users who posted in this thread nine years ago might not be the most sensible thing.
