I really like both (and not coming from a bias point of view, I have won countless times soloing on both)
Map 1 does require a little more skill than map 2.
Map 1 - You can go any route you like and still maintain the same gear as anyone else. This is more of a team map. You pretty much have to cycle between the Castle, Boat and Corn to maintain top gear.
Map 2 - You primarily go to the village first and try to loot any of the 18 chests there, and cycle between the Village and Corn for top gear. Whoever goes into the city is doomed to no gear, no food and lots of mobs. This is more of a solo map, where you can hog 28-30 chests in 2 small areas.
I have more of a fun time on 2, but it's starting to get boring for me as I haven't touched a skyscraper in more than a week.
