It is difficult to provide a definitive ranking of business schools as the best choice will depend on your individual priorities and goals. To determine which among IIM Udaipur, Trichy, Ranchi, and Raipur is the best fit for you, it is important to consider factors such as the curriculum and placement opportunities in your desired field, the focus on research, the availability of Students Exchange Programs and other opportunities for exposure, and the overall perception of the school.

If you have a specific field or area of focus in mind, you should look for a B-school that offers a strong curriculum and good placement prospects in that area. If you are interested in gaining hands-on research experience, you should consider schools that have a strong orientation toward research. If you are looking for opportunities to gain exposure and experience through programs like student exchange, you should consider schools with a strong track record in this area.

If you do not have a specific priority and are unable to identify a clear difference between the opportunities offered by different B-schools, you may want to consider their perception. While this can be difficult to quantify, their overall perception can impact the quality of your peers and the overall learning environment. To judge the perception of a B-school, you should do your own research and consider factors such as the reputation of the school, the accomplishments of its faculty and alumni, and the resources and support available to students. Ultimately, the best choice for you will depend on your personal goals and priorities.

Firstly let me clarify one thing. IIM Raipur cannot be compared to IIM Shillong because the latter is out of the league and is no longer a new IIM. Its worth and placements are much better than the newer IIMs and are in the league of old IIMs. We can only compare IIM Raipur to the 6 new IIMs namely Raipur, Ranchi, Rohtak, Trichy, Udaipur, and Kashipur.

After Shillong, one new IIM that gives an edge to older IIMs is Ranchi mainly because it works under the mentorship of IIM Calcutta. The placement statistics of IIM Ranchi are a testament to the same.

After Ranchi comes to Trichy, one of the fastest-growing IIMs. It has a decent placement scenario and a better professional approach.

Raipur and Udaipur are almost similar and are better than Kashipur and Rohtak. Raipur especially enjoys location advantage being situated in the capital of Chattisgarh. The faculty base is also quite learned and the institute has proper connectivity.

Kashipur has many connectivity issues but is famous for its guest lectures and interaction with industry experts. 

IIM Rohtak is the last in line mainly because of its pathetic placement scenario which overshadows its vicinity to Delhi.

So the final order is

Shillong>Ranchi>Trichy>Raipur=Udaipur>Kashipur>Rohtak

The distinctions between Ranchi and Trichy are razor thin. Both second-generation IIMs are performing admirably in their respective leagues. Here is a comparison of Ranchi and Trichy based on various parameters. Raipur and Kashipur lag far behind these two IIMs.

Parameters:

• Placements: Ranchi and Trichy have remarkably similar placements. Ranchi's average package is 16.62 LPA, while Trichy's average package is 17.01 LPA.

• Campus: Trichy, hands down, for campus life. Trichy has a modern 175-acre campus with all amenities. In 2021, the institute began moving to a permanent campus on a 60-acre plot in Dhurwa.

• Locational Advantage: Both have a geographical advantage. Ranchi is near XLRI, Jsr. Trichy is conveniently located between Bangalore and Chennai. Trichy is also home to NIT Trichy, the best NIT in the country.

• Perception: Trichy's perception is rapidly expanding. It is fairly obvious from all B-school rankings. So, with the exception of marketing, you can choose IIM Trichy over IIM Ranchi for any specialization. Ranchi's marketing is effective.

Therefore, taking everything into account, the final ranking will be Trichy>Ranchi>>Raipur>>Kashipur.

Your choice of college depends on your personal preferences and interests. One college might be suitable for you but not for others. So your question is subjective and cannot be answered directly. 

Every individual ranks a college depending on his own perspective and goals.

I think the best way is to contact students or pass-outs from respective colleges, collect data and then make a decision based on your research and then your preference. You can also look up the official websites of the college to collect relevant data. Find out the parameters that matter to you the most in your choice of college. Some include placements, diversity, location, batch strength, or faculty. Do your part of the research and then choose the college that fulfills the maximum boxes in your priority list.

I think the single most important reason why IIM Raipur and Ranchi are considered below IIM Udaipur is the lack of proper marketing. IIM Udaipur has managed to make its mark through enough marketing and promoting research culture. The IIMRs is also flawed in the sense that they are located in extremely poor economic states. This flaw overshadows all their features and the fact that they have better placement scenarios than IIM Udaipur.

Every IIM has set a certain goal and is gradually climbing the ladder to reach its level of excellence. The same is the case with IIMRs. In just a few years these two will be among the best IIMs in India.
