Oh there are a lot of good maps, but also funny maps, both good and funny maps are more rare.

Official maps
Radar
Oasis
Goldrush

Custom maps
Carentan
Warbell
Caen
Supply Depot
Marrakech Streets
Bremen
Braundorf
Adlernest

I am sure there are more, but these are the one I think of when a new map loads or what I look for when it is Map-Voting
