If you are an academically interested person, both NIT Kurukshetra and PEC Chandigarh will cherish you, and you will get very good opportunities in both colleges. Here are some key points to consider when deciding between the two:

Commonalities between the two colleges:

• Both are constituent colleges of Anna University, so they share certain components, including course offerings, examination schedules, and university calendar events.
• Faculty transfers between the colleges occasionally, and collaboration in research is not uncommon.
• Both colleges have bright and interesting peers and professors to inspire you.

Where PEC Chandigarh is better:

• Scale: PEC is a bigger college with more people.
• Exposure: PEC is in the center of the city and is a well-known institution in the area.
• Faculty: PEC's faculty in the CS department has more doctorates, and the department has been around for a few decades.
• Seniors: PEC has been teaching computer science for longer than NIT Kurukshetra, so there are more alumni out there creating and contributing to organizations.
• Sponsors: Due to the above reasons, PEC has very good sponsorship for college events.
• Campus: PEC's campus is beautiful, with easy access to AU events like counseling, placements, and festivals that happen in AU grounds.

Where NIT Kurukshetra is better:

• Seniors Link: The link with seniors is much stronger at NIT Kurukshetra, with a strong emotional dimension to the senior-junior relationship.
• Entrepreneurship: NIT Kurukshetra has an incubation center on campus, which is great for students interested in starting up early on.
• Programming: NIT Kurukshetra has a good competitive programming culture, with consistently high rankings in the Regional ACM-ICPC competitions.
• Campus: NIT Kurukshetra's campus is conveniently located near Chromepet Railway station and the bus stop, making it easy to get around the area. The campus also has a rich history, serving as a hanger for wartime planes, and the aeronautics department hosts a couple of legacy planes for people to admire.

Ultimately, the decision between NIT Kurukshetra and PEC Chandigarh depends on your personal preferences and priorities. Consider factors such as location, campus facilities, faculty, and alumni network when making your choice.

I don’t think comparing both the colleges i.eAnna University College of Engineering and NIT Trichy is justified. This is because both are equally good in almost all the parameters. Both ranked among the top Engineering colleges in India. I have made a slight comparison based on the following factors to make a better choice:

Placements: NIT Trichy has an upper hand in placements. More core companies visit NITs in general than CEGs. This is because NIT is an established brand name.

Higher studies: CEG is slightly privileged in this aspect as it considers the TN state boards marks whereas NIT considers JEE performance. So the former is easier than the latter.

College life: College life at CEG is better because of its location. You can eat outside the hostel as many restaurants are available near the college. But NIT Trichy is far from the city so options for exploring are fewer.

Lastly, keep in mind that if you are choosing NIT then go for Trichy or Kurukshetra only. Don’t go for any other NIT leaving CEG.

NIT Puducherry is very new compared to College of Engineering Guindy (CEG). Let me share some points which might help you decide.

• CEG is very old and experienced as an educational institution. It has well-established CSE and ECE departments with exceptional and updated lab facilities.
• The syllabus is more or less similar in both colleges.
• CEG has a more competitive student crowd which eventually helps students to boost their morale. 
• Due to its years of educational experience, CEG definitely has a better placement record than NIT Puducherry.

It is recommended that you go for CEG if you have to choose between these two. But if your choice only is NIT Puducherry then you can opt for it. It is a good college but as it started functioning recently, it is better to go for an experienced one.

One of my friends studied at College of Engineering Guindy (CEG). According to him, it is a good institution, CSE being the highlighted department. Let me share the details I got to know from him.

• CSE students are very much dedicated to their projects and assignments.
• The faculty members are also very cooperative and highly experienced in their respective fields.
• CSE always had and maintained a good placement record.
• The campus itself is very huge, providing an appropriate place for students to study.
• There are active clubs and international techno-management Fest 'Kurukshetra' and cultural fest 'Techofes'. 
• They also have a club for quizzes, Industrial quality maintenance, social activities, photography, college magazine, all of which are active throughout the year.

Therefore, after considering everything I think it will be better to join CEG, as it will develop you to achieve success in anything.
