Albion by Goombac for its wonderful city icons and the other beautiful touches that elevate the map, though it is a bit loud for my tastes.
OCD Mountains by Xpian for its OCD mountains duh. And also the details in the insets.

I would have also gone for Carbus' City of Fingard map because it is wonderful, but felt it fell too far out of the parameters of what I felt the contest was looking for.
