DTU should be your priority. It is one of the oldest Indian Engineering institutions. It has a brand name and a good reputation. It has better placements, campus, college life, location, etc. than COEP. Only NIT Trichy and NIT Warangal are on par with DTU. Mechanical is a renowned branch at DTU. The Mechanical department has many innovations to its credit. For example, the first Biodiesel Lab in India.
I know someone who did his B.Tech Mechanical from COEP. He chose COEP over a top NIT. According to him, it was not a wise decision for his career. Teaching is done mostly in Marathi at COEP. Some of the faculty members are underqualified and not up to the mark. This made him lose interest in learning and resulted in poor personality development.
At NITs, you study with people from across India and this offers exposure to different cultures. The NIT brand also has its added advantages. NITs have a standard grading system known in the industry. When you graduate from COEP and go to, say IIMs, the grading system at COEP causes a lot of hassle. COEP does not offer cross-culture exposure. Though the labs at COEP are big, the equipment is outdated and non-functional.
A benefit is that COEP is located in Pune which is an automotive hub. Therefore, Mechanical students get to connect with the automotive industry. Pune automotive industry has a large number of COEP alumni. All this allows you to do a lot of live industry projects while on campus.
Overall, choose DTU and if you do not get admission into it, go for lower NITs.
DTU is a tier 1 engineering college and has a distinct legacy of its own. It is one of the oldest engineering institutes in India and according to the 2020 NIRF Ranking, it ranks 34th among the top technological institutes in India. The placement scenario at DTU is quite impressive and students receive an average package of 6.5 LPA on placement drive.
Although COEP is also a reputed college, most of the students are local and Marathi speaking. So if you are comfortable in Marathi and can strike a balance between Marathi and English, then you might consider COEP. The biggest advantage of COEP is it is located in the automation hub Pune which helps in the placement, especially for the mechanical branch.
Although the ‘NIT’ tag offers certain advantages, except for IT and ME branches the placement scenario in lower NIT’s is not up to the mark. Besides, these lower-ranked colleges also offer fewer opportunities for startups and entrepreneurship. DTU on the other hand has an excellent coding culture and conducts a vast number of fests for coders. However, a major difference between DTU and lower NITs is that the fee in the latter is much less as compared to the institute fees in the former. All NITs have a common fee structure as they all come under the reserved list of “Centrally Sponsored Institutes”. Furthermore, NITs also offer many scholarships for students.
However, considering all the aspects and the associated pros and cons, DTU should be the first choice.
