You cannot get a comparative list except from users that have experienced Bitcoin in different countries. I can tell you from the point of view of a Nigerian as well as some other African countries.
You will need to collect the experiences of forum users from Asia, Europe, America (North and South) and then draw a comparison on which is more friendly than the other.

The list may not be too comprehensive but can give a general idea of which is best. A good questionnaire will also help shape the answers.
