Hahaha....
I do think I could be a brand whore indeed...from the sound of it....I am perhaps in denial....
Actually if the intention to stay in London / Europe is there and is possible, I don't see much difference between LBS and SDA Bocconi, as Bocconi has a strong network within finance in London as well.
However that said, I will like to have the flexibility to be able to choose to come back to Asia / Australia should there be better job opportunities in Asia / Australia after the MBA.
I have done both consulting and finance. Though it is good to have the single-minded focus on the area where you wish to end up working, in this tough economic climate, sometimes you have to take the best opportunity that is offered to you at that point in time, be it consulting or finance.
You have no intention to stay in Europe afterwards? If so, why take the expense and go to LBS? If you intend to stay in Australia, why not MBS or AGSM (god knows what they are called now!)
