Lots of things to think about here. There is no definitive answer as to whether an MBA from the UK or the US is better IN ABSOLUTE.....and in fact that question is irrelevant...the question I'm always asking myself is: Is this school/program length/brand/program/etc. better FOR THIS INDIVIDUAL. Whether something is right for an individual depends on his goals.
You said you wanted to work in MC but you didn't mention whether you would stay in the US for a couple years, stay permanently, go home to China immediately....etc. I always have a lengthy conversation with clients about short and long term plans and alternative scenarios (life doesn't always work out as planned) - then we weigh the brand value of a school or program within that context. I'm assuming you want to work for a few years in the US - in that case a US MBA is really the only option because after completing your MBA you have a working visa in the US for 1 year I believe (and the employer can help you renew afterwards). It's going to be pretty hard (but not impossible) to land a job + employer willing to sponsor your US visa if you're coming from EU. Since you also feel that a US MBA has more cache internationally it would seem that a US MBA is the right choice.
The other option is doing LBS or INSEAD - then you might work in the EU/UK post-MBA instead of the US.
Can you get into a M7 school is the question.
You're too old for Stanford (I'm glad you also recognize that). Wasting time applying there is just going to suck your energy away from more promising applications. HBS, like Stanford, is trending towards younger applicants - you're technically too old for HBS as well but if you had to apply to either Stanford or HBS, I'd say apply to HBS.
You could do a shorter program - Kellogg has a 1 year MBA and I had an international student from McKinsey choose that over a 2-year at LBS this year because he thought it had a better brand value in the US and in his home country. With a one-year MBA I feel pretty confident that you could get back into the corporate world/development - without an internship it might be difficult to land an associate role at a top MC firm BUT I think that will depend on how aggressively they are looking for people with infrastructure backgrounds (you should reach out to some people who went from infrastructure to MC and ask for their opinion).
I have read that each school has its strength, e.g. Wharton with finance, MIT with supply chain management etc. But I am not sure if I should follow a particular strength of the school or its overall brand value.
In my class at MIT there were not many people specifically interested in supply chain - there is the LGO program for that. Likewise not everyone at Wharton does finance - there are also people who do MC, marketing, start-ups etc. I wouldn't be too drawn in by the stereotypes of each school - you'll limit yourself if you do. Each school has a mix of students - but it is true that some schools have better recruiting opportunities in certain areas. MC you'll find at all top 15 schools.
So what do we have now? 1 year Kellogg or 15 mo Columbia, 2-year Wharton (they place a lot of MCs), Chicago Booth, MIT? or INSEAD, Oxbridge, LBS.
I offer free school selection services (as well as ding reports) so feel free to reach out and we can set up a call. I say that because I think this is a complex story and I'm going to end up writing a book here on the forums before I'm really able to hash everything out.
