Dubai just gets too overwhelming for me. Yeah they have a ton of huge buildings but it seems too overdone - it has no substance.
There's so many buildings that it's unexciting to me when they get another 20 supertalls, and have to build mega-talls just to make a break in the skyline.
I look at it kind of like Las Vegas, but in the east. If there's a city for excessiveness, then both of those are definitely the appropriate candidates.
I think in Duba's case, everything is pretty new, thus you get less variation in building design.
