If you are evaluating the institutes based on placements, then you will be pleased to know that IIT Delhi ranks 28th position in the Top 50 of Times Higher Education Global Employability University Ranking and Survey.

However, I feel placements should not be the determining factor as the IIT tag will get you placed with a good package irrespective of whichever IIT you choose. The primary determining factor should be your inclination towards a specific branch. If you target a specific branch just based on placements, you are likely to lose interest soon. This will result in a frustrated career. In fact, I have seen many students opt out of CS just because they realize that it’s not their cup of tea and go for average branches that intrigue them genuinely.

Here is a comparative analysis of placements of both the institutes

The answer to your question is objectively based solely on your inclinations. IITs might offer a better ROI than IIMs. But had I been in your place I would have gone for the newer IIMs like Kozhikode or IIM Ranchi which is one of the fastest-growing IIMs. The reasons for taking this decision would have been

• Better opportunities in finance, marketing, and consulting domains.
• Better placement opportunities 
• Better industry exposure
• The prestige of being a part of the IIM alumni network
• The IIM tag 

All these points make IIM a more tempting choice. Yet if you are tight on budget and just want to go for the Operations domain IIT will do fine for you.

While the newer IIMs like Ranchi, Trichy, and Udaipur have a good reputation, IIT Delhi still offers certain advantages that make it stand out as a better option. Here are some reasons why you should consider IIT Delhi for your MBA:

• Placements: IIT Delhi has an impressive placement record, with several top-notch companies visiting the campus for recruitment every year. The average placement package for MBA graduates from IIT Delhi is also higher than that of the newer IIMs.
• Exposure: IIT Delhi has a larger and more diverse student body, which means that you'll have more opportunities to interact with students from different backgrounds and gain exposure to different industries and sectors.
• Faculty: IIT Delhi has a highly qualified and experienced faculty, with several professors who are experts in their fields. This means that you'll receive high-quality education and training from some of the best minds in the business.
• Academics: IIT Delhi's MBA program is highly regarded and has a rigorous curriculum that covers a wide range of topics, including finance, marketing, operations, and strategy. This will give you a strong foundation in business fundamentals and prepare you for a successful career in any industry.
• Alumni Network: IIT Delhi has a strong alumni network, with several successful MBA graduates who are now leaders in their respective industries. This network can provide you with valuable connections and mentorship opportunities that can help you advance your career.

While the newer IIMs are also good options for an MBA, IIT Delhi stands out as a better choice due to its strong reputation, impressive placement record, diverse student body, and highly qualified faculty. So, if you're looking for an MBA program that offers the best of everything, IIT Delhi should definitely be at the top of your list.

Both IIT Delhi and IIT Ropar are highly reputable institutes in India, and both have strong programs in production industrial engineering and computer science engineering, respectively. However, if I were in your place, I would have chosen IIT Delhi Production and Industrial Engineering. Here are some strong points supporting my stance

• Location : Located in the capital city, IIT Delhi offers great access to coaching institutes for preparation for IAS, IES, GATE, or any other competitive exams. This won’t be possible at IIT Ropar.
• Reputation: IIT Delhi's Overall ranking by NIRF is 3 out of 200 colleges in India in 2023 while that of IIT Ropar is  33 out of 200 colleges in India in 2023.
• Reputation: IIT Delhi is not just an institute it’s a brand that every recruiter and student is aware of.
• Curriculum: IIT Delhi Production and Industrial Engineering has courses similar to Mechanical students so the job opportunities are also similar. Additionally, you can learn some management skills through subjects like industrial engineering subjects Quality control, Operations research, Production planning, and control, etc 
• Placements: IIT Delhi has a track record of excellent placements way better than IIT Ropar. It can further be understood through the table below

Considering everything, IIT Delhi is a better option than IIT Ropar. The opportunities, brand name, and academic environment you will have access to will be unmatched. However, if you have a specific inclination towards the CS branch and want to pursue a career in the same, you can also consider joining IIT Ropar as the CS branch has diverse job opportunities even for the average students.

Ranking-wise the preference order of the above-mentioned courses is 

IIT Delhi > IIT Kanpur > IIT Roorkee > IIT BHU

Based on their closing rank, the branches can be arranged in the following order 

Chemical>Metallurgy>Textile 

This was based on general data, but if you have an inclination towards a specific branch, then go for it without much hesitation. Your passion will keep you motivated despite various challenges thrown at you. But in case you have no specific preference, then you can consider the college and branch ranking to make an informed decision.

Apart from CS and Electrical, students from most branches opt for non-core jobs which require much more than their core academics for placements. In that case, you can prefer IIT BHU over IIT Roorkee.

Ultimately, the final decision is yours to make. Choose wisely considering various factors like location, friends, etc,
