Hi Duncan,
I am from India and I have decided to pursue MBA this year from Europe. I am planning to apply at Corvinus Budapest (AMBA), MIB Trieste (AMBA) and Luiss Business School, Rome (AMBA and EQUIS) for their reputation among the employers in Europe. I don't want to compromise with the quality of learning because if the degree is accredited I can try to find a job elsewhere or in India through connections as we dont know the impact of brexit in Europe.
Will it be fine if I choose Luiss over other two schools based on the fact that it is double accredited and is recognised as an educational institute unlike MIB and has partner schools in India like SPJIMR which seems convincing that the Luiss degree will be recognised in India.
I checked www.anabin.de, a german website to check if the degree is accepted by German employees/govt assuming if the degree is recognised in germany it will most probably be accepted else where.

Labour markets are profoundly national in Europe, and even regional (Trieste, previously Austria's major port, has a distinctly more central northern culture than Rome). Hungary seems like a really brave choice for an Indian right now. I wouldn't want to live under that government. Yes, those will be recognised as real degrees but if you want to work in Germany, get a German degree. 

Italy's economy is expected to revive quickly as it has received 192 billion Euros from European Commission and it is expected to see new businesses coming up. I want to bet high on Italy. So on comparing these two schools, which one of these looks like a stronger option ?

None of these is a very good choice for international mobility, but MIB is certainly the better.
