personally, i think Biomes of America is the best of the lot, it's a work of art, and that's probably the general opinion here too: https://www.warzone.com/multiplayer?GameID=21051408
although alot of people like Africa, and Gotham is popular on QM like TBest said. Master Mania is considered weak by most. Landria is new and experimental. Don't know if anyone plays Europa Magna, and Aklog Island never took off (it's also not strategic in that the map is symmetrical).
to find example games of some of these templates, although others you'll have to ask for them. just don't let Cowboy convince you to join that ladder ;)
