It varies a lot for me honestly. Generally speaking I find the maps to be much more interesting and fun to play than before GS but then sometimes you get those maps that you mention where it's just a pain to navigate through mountains and you don't really have the space to do anything. That's when 1upt really is a pain, when there are too many units and too many passes to move comfortably. But most of the time the maps feel fine to me. I haven't played any Pangea as of yet though, I've only played Continents.
