Hello,
I posted a thread a couple of days ago asking why South Korea gets overlooked by most Asia-bound tourists. The feedback helped me understand why. Moving on with my queries, how do South Korea’s big cities-Seoul and Busan-compare (sightseeing, energy/buzz, architecturally) to Asian urban hotspot/‘must-see’ destinations like Hong Kong, Beijing, Shanghai and Tokyo? Do you think Seoul and Busan are similar in caliber or do you think they are simply ordinary developed Asian urban centers?What about it? I've never been there? Are you implying that it is a world-class city like Shanghai or Hong Kong or Tokyo?

Busan is small - about 4 to 5 million people, it is not in the same catagory as Shanghi or Tokyo. Perssoally i prefer Seoul to Shanghi, have not being to Beijing or Tokyo yet.

Well Seoul has 2 World Heritage Sites, 3 if you count the suburb of Suwon. Tokyo, Hong Kong and Shanghai do not.
So, for history Seoul is in 2nd place after Beijing.
I've just moved to Seoul and have been to all the other cities (except Busan), and it seems to me to be massively under-rated.
