UCD Smurfit or Manchester Alliance?

Hello everyone, I got admitted in both business schools, and now I have to choose. 
This is my profile: I'm an Italian student currently at the third year of my bachelor degree in economics, and I'm following a double degree program in international business at Montpellier Business School. At this moment I don't have work experience, but I'm planning to do an internship during this summer (if I'll have enough time while writing my thesis).

My plan for the future is to work in a multinational company, possibly in strategy or sales. The sectors I'm more interested in are luxury and tech.

These are the programs I got admitted in:

-MSc in Strategic Management at UCD Smurfit

-MSc in International Business & Management at Manchester Business School 

Counting the current situation in both the countries, which program would permit me to have a better start of my career, and which university is more prestigious between them? 

Also, is it easier to earn a high salary in Ireland or in the UK?

A big pro of UCD is that I would have a mandatory internship, which I think it's useful. But I could get an internship in MBS too.
