Honestly speaking, both Thapar University and Manipal University are reputable institutions for a B.Tech in computer science. So the decision on which one is better for you ultimately depends on your personal preferences and priorities. is 

Thapar University is a highly esteemed, private engineering and technology university located in Patiala, India. Known for its strong academic programs and rich research culture in computer science, this university has it all. Additionally, it offers a range of student services, including career counseling and internships.

Manipal University, on the other hand, is a private university located in Manipal, India. It is one of the oldest and most established universities in the country and is known for its iRobot programs in CSE. The university has a number of student-driven bodies that promote extracurricular activities.

Some factors to consider while choosing between the two include 

• Proximity to hometown
• campus life
• Fees and other expenses 
• CSE Program offered

Both the colleges are almost similar in all aspects. So what actually matters is that if you live in the North, choose Thapar but if you are from the south choose Manipal. Both universities have the same fee and both are equally reputed private colleges after BITS. So I would suggest that whichever college is near your hometown go for it.

Ultimately, both universities are highly esteemed institutions and either one would be a decent choice for a B.Tech in computer science.

One of my friends was selected for the 2018–22 batch of Mechanical engineering. However, she was not very inclined towards joining it. Mainly because she was not very passionate about Engineering.

I will suggest you join TIET only if you are an avid fan of Engineering and are considering it seriously as a career option. But I personally feel that IIM is a better option if you aren’t sure about Engineering. The IIM tag offers enough credibility to make it a worthwhile course.

My friend's marks were not very good so she could not understand how she had made it into TIET. This altered her decision to pursue engineering. She further told me that the curriculum and campus life at IIM Rohtak were not as substandard as it is rumored to be. So it’s high time you conduct thorough research because this decision is the turning point of your life.

Both branches are excellent. You must prioritize your interests. If all three colleges had CSE, PEC would have been the best option. All of these colleges offer comparable placements, with PEC having the upper hand.

In this case, however, it is clear that the average package in ECE would be lower than in CSE. City-wise, Chandigarh is unquestionably the best option, and the exposure you will receive at PEC will be slightly better.

The most significant advantage of NIT Jalandhar is that you earn the title of 'NITian,' as well as the opportunity to study in a nationally significant institute. You will have an advantage over students from these institutes in the industry because of this one factor. That speaks volumes about the opportunities and jobs available.

So, in that order, NIT Jalandhar > PEC ECE > Thapar CSE.

However, if you get CSE at PEC, choosing between NIT and PEC will be more difficult. However, you should choose NIT Jalandhar. The rest is entirely up to you.

Rather than comparing the colleges, it’s better you identify your area of interest. Your own perspective gets to decide the college best suited for you. My friend is an IIT Ropar Electrical Engineering pass-out. She made the decision after considering the following aspects:

• Overall Development: IIT Ropar is a student-run college. The students here are the fuel driving the college. Most of the activities from the orientation of new students to the mentorship of juniors during placements are handled by the students themselves. These opportunities help them identify their own true self and capabilities. They just don’t grow academically but also as a whole.

• Interdisciplinary Learning: IIT Ropar promotes interdisciplinary learning. In fact, many EE students take up CS courses as electives and end up with CS jobs.

• Brand Name: No matter how much one devalues this aspect it is indispensable. The IIT tag you will carry throughout your life will help you get admission to higher education and also jobs. 

• Crowd: The crowd at IIT is one of excellence. Everyone is ambitious and here to achieve great heights. These peer groups become a source of constant inspiration.

• Alumni Association of IIT: This plays a significant role in developing and guiding placement drives at IIT Ropar. It offers mentorship to students and works with placement cells to ensure the best placements.

You can consider the same factors and compare the other two colleges. But I think IIT cannot be compared to just any college. 

Unlike the general opinion that NIT Jalandhar is better than Thapar University just because of its NIT title, I have a different opinion. I think Thapar University should get the recognition it deserves. Some points in favor of my opinion are:

• The CSE was renewed by Trinity College, Dublin. The curriculum is way more advanced than that of NIT Jalandhar. The latter has an outdated syllabus which is not relevant to the industry.

• Many technical societies help inculcate special skills.

• Placements for CSE are excellent at Thapar University.

• Coding culture is witnessing a spike over the few years. 1st year students are getting selected for GSOC

• The research culture at Thapar University is better than that of NIT Jalandhar where no one is interested in writing research papers at all.

• The infrastructure is also better at NIT Jalandhar.

• The location of Thapar University makes it easily accessible to restaurants, cinemas and other facilities.

• There are various coaching institutes in and around Thapar University for GRE/CAT/IAS/GMAT.

All these points clearly prove that Thapar University is better than NIT Jalandhar.
