Neither the MBA nor the MSc is inherently better; each one is better for certain circumstances. I'm not sure about the requirements for the MSc at those particular schools; most likely the schools' websites would have a "profile" of its students and you could see how you compare. Also, "career prospects" is so broad - what career? I suggest that you define and work back from your goals, determining which type of program would best serve your needs.
