Taiwanese Credit Cards - What is in your wallet and why?

Obviously I will need to do some personal research for this; However, I begin that research here on Forumosa since you all are a bank of knowledge…

Taiwanese Credit Cards. More specificaly, Master Card or Visa.

I want to know what you are carrying in your wallet and why? I have my JFRV ARC and now want to obtain credit. My wife will be co-signing since that is required to extend credit to foreigners.

The questions I have are:

What cards / banks do you think offer the best advantages and perks?

What cards / banks offer great interest rates?

What card / bank would you suggest?
