For solo mage, yes because sylgie provides more exp than berserkers that are in ulu1. And the map structure of ulu1 isn't very solo mage friendly.
I thought people were saying ulu 1 is for better drop to sell to npc (for mesos) and ulu 2 is for exp. fix me if im wrong
ulu 1 is a good map for duo with 2 mages (1 in bottom and 1 in top) cause it's big When soloing it isn't that good cause the map is a bit too large to be efficient, and also ulu 2 got that snake mob that gives more exp
