Both of courses offer different aspect of learning. Depends upon what parameter do you use to gauge which one’s better. Is it RoI or the learning and experience gained or the course fees?
Do choose the main campus for your studies, no matter what course you select. Satellite campus (Kengeri) sucks, no two words about it.
If it’s RoI, then go for regular 2 years MBA course, in-campus.
If you’re looking for learning and international exposure and two different degrees in a span of 2 years, then go for dual degree program.
If fees is the concern then obviously, regular MBA should fit your bill. Regular MBA will set you back by approx. 8L whereas Dual degree MBA will come around 15–20L.
Hope it helps. And best of luck for your future.
PS. There could have had been changes made to course and fee structure since I passed out; please do a fact check before concluding anything.
Edit: Out of dual degree programs, I’d chosen FHWS(German) even though VCU (American) was a better choice career-wise at the time but now it seems otherwise thanks to Trump
