No offense against any institutes as both of this institute are very well known and have their own pros and advantages. But if I were about to choose, I would have gone with NIRMA UNIVERSITY, AHMEDABAD. It's ranked among the top 30 B-schools of India and is one of the best in the field as well as it has great faculty and educational facilities along with well equipped labs and infrastructure. The placement opportunities are also decent.
