All the institutes you mentioned are quite different from each other and have no similar goals, visions, or outcomes. XIMB is a General Management institute while MICA and IRMA focus solely on a specific domain.

The most common evaluating criteria of aspirants for a B School are its ROI and Placements. Choosing a specific niche program might limit your opportunities and choosing it mainly because of its general parameters like ROI and Parameters might prove wrong in the long run.

IRMA is well known for its specialization in rural management, and its primary goal is to bring about a change in the rural sector of the country through professional management. As a student, you will acquire knowledge of the principles of general management, and certain social and liberal arts subjects.

The main highlight of the institute is its three internship segments. Through this program, you will get to witness rural realities and society through a different lens, and pave your way to an excellent career.

The question should be which one is better for me. Because one course might be good for you but not for others while the same course might be good for others but not for you. So check what you want from the course and then decide which one is best for you. 

If you are just passionate about digital marketing and are serious about working in an organization for the same, then the MICA program is the best one for you.

But if you want to broaden your options and look everywhere at once, then IIM Raipur is a good choice for you. It’s a good choice because

• The IIM tag
• Best faculty 
• Much better placements 
• Student Exchange Programs 

IIM Raipur is however not a probable option if you are just into digital marketing. This is because it’s not definite if the placement opportunities offered by the visiting companies match your interests. So make a choice after thorough research and thinking.

If you're looking to specialize in marketing and work in fields such as strategic communication, advertising, and media management, then MICA would be the perfect fit for you. They offer a range of courses and programs that focus specifically on marketing, making it an ideal choice for those who want to go deep in this field.

However, if you're an engineer looking for a more general approach to sales and marketing, you may want to consider NMIMS Mumbai, SIBM Pune, or IMT Ghaziabad. All three institutes are similar in their approach to marketing, but each has its unique advantages and disadvantages.

NMIMS Mumbai, for example, has a higher cost and a smaller campus compared to SIBM and IMT. However, it also boasts a strong brand and alumni network, which can be very advantageous when it comes to finding jobs or internships. Additionally, the packages offered by NMIMS are generally higher than those at IMT and slightly better than SIBM.

On the other hand, SIBM Pune and IMT Ghaziabad offer a larger campus and a more affordable cost of attendance. However, they may not have the same level of brand recognition or alumni network as NMIMS Mumbai.

Ultimately, it comes down to what you value most in an institute. If you want a strong brand and alumni network and are willing to pay a higher cost for it, then NMIMS Mumbai might be the right choice for you. If you're looking for a more affordable option with a larger campus, then SIBM Pune or IMT Ghaziabad may be a better fit.
