I guess if you take “Frontierland” totally literally and therefore remove Critter country and New Orleans Square, then sure. But to me those all occupy the same space in the park and should be compared together. The space around the River is all essentially one land in almost everyone’s mind. Not counting DL’s Splash just cause it is technically “Critter Country” or “Bayou Country” seems silly.
I, and many, prefer Pirates to TSI.
Better town area I’ll give you. But that doesn’t matter as much to me compared to New Orleans Square and all the attractions.
