Firstly let me clarify something. The 3-year work experience is not a suitable deciding factor for choosing a college. You should decide on a college on the basis of these parameters

• Placements 
• Brand value
• Batch-size
• Alumni Network 
• Location
• ROI

Now I will further compare the pros and cons of NMIMS and newer IIMs

Pros

NMIMS

1. Has a better location than Trichy or Udaipur 
2. Has a stronger alumni base
3. Is good for a career in Finance

New IIMs

1. The IIM tag in itself is a major advantage 
2. The new IIMs are growing at a good speed
3. The Batch-size is smaller than NMIMS

Cons

NMIMS

1. High fees
2. Large batch-size
3. Deteriorating brand value
4. Average placement opportunities 

New IIMs 

1. Weak alumni network 
2. A slight location disadvantage when compared to NMIMS

Now it’s your job to analyze which pros are more important for you to avail and which cons can be a major hindrance in your career.

Given the two chances, I will definitely join IIM Rohtak over NMIMS anytime. The reasons for my choice are

Campus: The newly made campus of IIM Rohtak stretches over 150 acres and is loaded with top-notch facilities. Although some might consider its location at a disadvantage to NMIMS, in reality, it is just an hour's drive away from Delhi.

Placements: IIM Rohtak has an upper hand in placement opportunities as well.

Pedagogy: You can never compare the pedagogy of an IIM with any other B School. It’s very rigorous and the curriculum does not focus on academics, but also on exposure. This exposure is brought by events like TEDx and Marathon where students learn how to manage. Guest faculties from other IIMs, institutes like MDI, and senior management from top firms visit the campus for industry exposure. 

Fees: IIM Rohtak- ?9.9 Lakhs (1st Year Fees)NMIMS- ?11.95 Lakhs (1st Year Fees). Despite being an IIM, Rohtaks fees are lesser than NMIMS.

Peer Learning: The peers are some of the most talented people you will ever come across. They have gotten into IIM with a percentile of more than 99.5. Moreover, there is a healthy blend of freshers and experienced students to promote effective peer learning. Most activities are conducted group-wise and each group comprises students from different backgrounds.

I hope these reasons might have cleared all the remaining doubts you had.

Before answering your question let me draw a comparison between both the colleges on the basis of the given factors

If you are still not satisfied, let me tell you one very important point. Choosing NMIMS will make you a BBA graduate only whereas the IPM program at IIM Rohtak will make you an MBA graduate. So choose wisely!

Rather than judging your decision, I will list down some merits of both colleges and leave the rest for you to choose from.

Reasons why one should choose IIM Kashipur over NMIMS:

• Smaller Batch-size: IIM Kashipur has a relatively smaller batch size than NMIMS. This means the placement opportunities will be better and attention given to each student will be more.

• Lower fees: Mumbai fees are around 21 lakhs for two years. Also, it does not include the accommodation and food expenses that a person will have in the two years. The minimum expenses in a city like Mumbai will stand at 20000. The total fee is much higher than IIM Kashipur ( INR 1730000).

• Specializes in Operations: The leading domain of IIM Kashipur is operations whereas NMIMS has limited scope for the same.

Reasons why one should join NMIMS:

• Better opportunities in terms of companies, packages, and roles than any other new IIM 
• Better location than the new IIMs
• Strong alumni base

So if you are confident that you can remain among the top 200 go for NMIMS, else IIM Kashipur it is.

In my opinion, the best course among these is IPM. Some might even think I am a little biased towards this course but in reality once you learn the advantages of this program you will change your mind.

The Programme consists of 15 terms spread over a period of 5 years, with each year having 3 terms of 3 months. The subjects of the initial 3 years focus on the foundation and the last 2 years have core subjects that focus on Management.

• The programme is designed by renowned experts.
• IIM-I tag
• Amazing infrastructure
• Excellent faculty 
• Extensive network of alumnis
• Peers from diverse backgrounds (The last 2 years are along with PGP students )
• Great placement opportunities 
• Wide range of co-curricular activities

Cons :

• Programme is new so recruiters and big companies don’t trust it much
• It experiences bias when compared to the old PGP model.
• In case one doesn't like the programme, you can not change the stream again.
• IPM offers very limited scope
• No specialization 
• Freshers are not much preferred in comparison to experienced placements.
• High fees

Still if you are not convinced that IPM is the best alone the courses you mentioned, the order for the other courses is

SSCBS> NMIMS> Christ

The only advantage the other courses have over IPM is that their model is tried and tested and open to lesser risks. Hence the scope is not that much limited.
