I will do a brief comparison between the MBA programs of the 2 institutes based on common parameters and leave the final call for you to make 

• Brand value: IIT Delhi enjoys international recognition while IIM Shillong offers the much coveted IIM tag. However, being a new IIM, its tag does not hold much value in comparison to IIT Delhi's tag.
• Fees: The MBA program offered at IIM Shillong costs a whooping ?14.6 Lakhs while that at IIT Delhi costs around INR 10.4 Lakhs saving you a few Lakhs.
• Location: Due to its central location, IIT Delhi offers much more opportunities in terms of exposure and placements. Located near the IT hub Gurgaon, it attracts many startups that come with internship offers. IIM on the other hand is located in the North Eastern part of India and lacks the necessary industrial touch.
• Infrastructure: IIT Delhi is one of the oldest IITs lacks in terms of infrastructure when compared to the newly built IIM Shillong which has a dreamy campus.
• Top sectors: IIT Delhi is well known for its specialization in IT/Consulting, and Operation whereas IIM Shillong’s top sectors are Sales & Marketing, Finance, and Consulting.

Now weigh the pros and cons of both and make a wise decision based on the same.

Among these, NITIE Mumbai is the best institute for an MBA. It is considered the Mecca of Operations and SCM. The Ops and SCM job profiles offered at NITIE Mumbai placements are even better than the ones offered from these sectors at IIM ABCL. The final placement record for 2022 showed the average CTC is INR 24.51 LPA. Highest CTC offered this year was INR 49 LPA.  

Locational benefits, a huge alumni base, and a stellar placement record are some of the other factors that work in favor of NITIE.

It is true that IIFT Delhi has a strong reputation and a good placement record. Over the past three years, students have consistently earned an average salary package of INR 20 LPA or higher. In the latest placement drive for the 2020-22 batch of the MBA (IB) program, IIFT Delhi achieved 100% placements with 82 companies participating. The highest international CTC was INR 80 LPA, the highest domestic CTC was INR 46.5 LPA, and the average CTC was INR 25.16 LPA. Approximately 25% of the students were placed in the consulting domain.

When choosing a business school, it's important to consider factors such as placements, alumni support, exposure to the industry, and available resources like libraries and research papers. Location can also be a factor, as being in Delhi may provide more opportunities for exploration and connection with potential employers compared to Shillong. Ultimately, it's important to weigh all of these factors and choose the school that best meets your needs and goals.

MDI Gurgaon is a better option. It has a better location and offers good placement and return on investment. It is situated close to a major city. So, you will get better opportunities in terms of placements, internships, live projects, etc. 

It has a great placement record. During MDI Gurgaon placements 2022, more than half of the batch received salary package of INR 25 LPA. The average CTC for the whole batch was INR 23 LPA.
