This is my list for "Best-Looking from a distance" (Which is what really matters anyway.) :
Seoul is the most over-rated skyline...It's a sea of high/mid-rises without a clear focal area. and Kuala-Lumpur is over-rated for the opposite reason...it's just a summit (Petronas Towers) separate from any unified cluster. Shanghai is tall but it lacks unity...I included it in my list nevertheless.
