What is the Best Metro/Subway System in Asia?

What is the best metro/subway system in Asia? Let everyone hear your opinion in the comments section below: why do you like it? Is it because it is modern, clean, efficient?

Included are almost every major system in Asia. 2, 3, or 4 major systems were included for each country that has a metro system in Asia: otherwise finding footage for the systems in China would have made the video extremely long (along with other countries such as Japan and India). The video would be at least one hour long. Doha, Qatar and Jakarta were excluded since they are relatively new.
