For me, I felt like Oxford was a bigger brand name than INSEAD. Maybe it's not as highly ranked or as respected in business circles, but I believe it'll be worth more down the road in 10 to 20 yrs. I personally believ INSEAD's reputation has topped out, where as Oxford's MBA program still has a lot of room to grow.
I'm also thinking about a career in Asia, where the Oxford name probably opens more doors than INSEAD, especially amongst the old school bureaucrats that run most of China and Hong Kong. Also, as highly ranked as INSEAD is, I'm looking for a career in finance, and that's not its particular strong suit.
The final thing that swayed to Oxford was my campus visit to both schools. INSEAD felt like a high school campus whereas Oxford felt like a real academic institution with centuries of history. Not to mention you pretty much need to speak French to get around anywhere off campus at INSEAD.
So there you have it. Good luck with your apps!Posted from my mobile device
