Which is better as per placements and quality of education: GIM, SIIB, Fore IB, or KJ Somaiya?

Although all the B Schools you mentioned are very good, the one I would personally recommend is FORE. Some points that favor my recommendation are

• Location-based crowd: All the other colleges you mentioned have students mainly from Mumbai. But FORE located in New Delhi, the heart of the country has students from all over India.

• Placement: Here’s a tabular comparison of the average and highest CTC of the colleges. 

• Fees: 

GIM: ?18,31,200

FORE: Rs.16,98,000

KJ Somaiya: ?9.59 Lakhs (one year)

SIBM: INR 3.53 L - 16.62 L(for 2-3 years)

FORE offers industry oriented certifications and International Immersion Program. So looking at the overall picture we can say all 4 colleges give each other tough competition but FORE takes the lead.
