Undergraduate Master Degree vs Postgraduate Master Degree

I've heard people saying that if you apply for an undergraduate Master degree you will get MEng or MSci, and first doing BSc and then apply for postgraduate Master degree will get you a MSc.

Personally, I'm very interested in the specialisation of Artificial Intelligence inside the Computer Science master degree, so my questions are:

1. Is MSc at advantage when compared to MEng or MSci for oversea jobs in the US or Europe?
2. Which route would you recommend?
3. What is the main difference in the structure in the programme or assessment? (if any)
4. Would you rather spend your last year at other institution? If you do, will you feel out of place socially?
