In general the newer issue is closed as a [Duplicate]{.jbs-value} of the older one, but where the newer issue has a clearer description then doing it the other way round is ok as long as none of them has been [Fixed]{.jbs-value} already. If one of the issues has been [Fixed]{.jbs-value} the other one should be closed as a [Duplicate]{.jbs-value} of the [Fixed]{.jbs-value} issue.

I agree that in general the newer bug should be closed in favor of the older, but it's not just about a clearer description.  It could be that the newer bug has more useful, up-to-date comments, or it somehow has more helpful attention/visibility.  For example, I would avoid closing a public bug as a duplicate of a confidential one.
