Agency vs Independant

I will be in Hong Kong next week and was wondering if it's better to chose an agency or independent escort. I was thinking about "http://escortgirlshongkong.com" and I have messaged some independent escorts but none have reviews.

I found the massage parlors to be very affordable and sufficient.

But, the independents are fine.
