Hi Paradise911,
Congratulations on receiving so many offers. It is difficult to say which MBA program will help you propel your career in the SCM function. Nearly all of these schools offer a very General Management based MBA program, where the opportunity for super specialization is very limited. Infact most 2nd tier European MBA programs with small class sizes tend to offer limited specialization options and limited electives, so the focus broadly remains on general management, however you can tailor your learning profile according to your needs & career aspiration.
I would advise to choose between Vlerick & Smurfit as they are the best MBA programs in their respective countries. Vlerick is the very best in Belgium and Smurfit is the best in Ireland and their career services have fared very well in the past. Although Vlerick went through a very bad patch with its MBA placements sometime ago but has recovered substantially since then while Smurfit has been very consistent for years despite Ireland's dismal economic run. Nyenrode & Aston go out of the picture when you have an offer from Vlerick and I am not at all positive about Tiasnimbas, Strathclyde and Emlyon only because of their dismal Career services (as projected by their recent graduates), Emlyon in particular. All these schools will offer a very similar MBA experience & learning, just the one with a stronger career service will lead you to a better job. I will also recommend to check the list of electives related to SCM at these schools before taking the final decision.
Hope it helps.
