Well, with the lolcano, not many people like it, the Hale always hides in the lava, and the fact that thtere are so many difficult-to-get-to places you can be in, it's not a very likable map.
With Harukei Shrine, it's a pretty straightforward map. It's got a hill, a couple of buildings with not much hiding places in them, and it's a pretty nice looking map (Of course I only say that because I'm a fan of the thing). My bias aside, it's a good map.
