It depends upon what you think you will pursue as a career. Generally, there are transparent ways into monitoring whether or not an institute is really worthy, at least when considering the CSE department. 

• If you are more inclined towards pursuing a career as a computer programmer, then here are some websites you should definitely check out: CodeChef, HackerRank and CodeForces.
• These competitions apparently gauge the programming skills a person generally comes with, and whether or not they will be successful in relevant aspects. 
• These websites come with a neat leaderboard, including the ranks of coders assessed accordingly in terms of their programming skills. 
• The major upside of these sites is that the leaderboard arrives with the name of the institute these coders belong from. 
• This naturally helps to evaluate how reasonable an institute is. 
• You can moreover filter the leaderboards in accordance to the institute you prefer. 

Therefore, these features go on to provide more compact comparisons among institutes and can possibly help you decide which institute is worthy. However, it is best to also research more about the prospects each institute shares; and how they are in terms of placement, faculty, etc.

Thapar University in all aspects is a lot better than JIIT. But I am not quite aware of the EIC branch. You can interact with ex-students of the institute online, to get a better idea about the course. If you think it will be a better choice, go for it.

• According to placements, Thapar is much better than JIIT Noida.
• Most of the companies that participate in Thapar’s placement program are well reputed like Microsoft, Infosys, and many more.
• Thapar provides a better industrial exposure to their students.
• After graduating from Thapar you can opt for both government and private sectors.

Thapar University will be a much better choice than JIIT, as it is popular among students and professionals as well. Any branch at Thapar will prove to be more valuable than CSE at JIIT Noida.

CSE at JIIT is clearly better than ECE at Thapar. You must have a minimum JEE rank of 51,000 to get CSE at JIIT Noida. 

There are no state quota, caste quota, or NRI quota at JIIT but Thapar offers a 50% quota for Punjab state students. This results in a superior quality of students at JIIT Noida than Thapar. Due to quotas and an increase in the number of seats, anyone can get admission at Thapar University.

If a student has a 300,000 rank in JEE Main, he will not be able to gain a seat anywhere, but if he is from Punjab, he may be able to secure a place in Electrical Engineering in Thapar. This explains how Thapar's situation has deteriorated.

JIIT will offer you great exposure which is actually required in CSE with regular industrial visits. CSE has more scope in terms of placements than ECE. 

It would be advisable to choose the branch as per your interest first. And then if you figure out that you have an interest in civil engineering, you should go to Thapar. On the other hand, if you have an interest in computer science then you should go to Jaypee Noida. 

• Thapar University and Jaypee Noida are both good. 
• The main thing to be concerned about is your interest in the stream. 
• Both the colleges are very reputed but Thapar has a slight edge over Jaypee. 
• The placement record for Jaypee for the past year has not been as good as compared to the previous year‘s records. 
• But if you compare Thapar’s civil and Jaypee’s CS, then you should opt for CS at Jaypee.

Being a student of Jaypee myself, I can say that Thapar’s placement records are better, especially recently.

Many of the students do not find ECE as an interesting branch due to the following reason:

1. It is often seen that India has less scope in ECE among all the other engineering branches.
2. In the private sector, the value of CS/IT is more than ECE. They also have better packages than ECE.
3. If the student wants to go for PSU, there is greater scope in Mechanical or Electrical.
4. If the student wants to go for engineering services, Civil is a better option.
5. And if the student wants to go for higher education, any branch can be taken as per their choice.

Now, coming back to the choice between the two colleges, we know:

• JIIT Noida will help the student land a job after 4 years of engineering in ECE or any other branch in any MNC offering packages between 4-4.5 LPA.
• If the student wants to secure a big position in any Electronics company, then they will be in the top position among the ECE graduates.
• Very few core ECE companies visit the campus for recruitments and select a very less number of students.
• However, the students can also try for off-campus placements.
• The faculties at both institutes are good.

If the student wants to secure good, any college between the two can be chosen but the student will have to work hard. A lot of effort will be needed in ECE organizations.

Students who join IET Lucknow tend to have higher ranks in JEE (Mains) than JIIT Noida. But JIIT Noida is mostly preferred by students, here’s why:

Location

• Due to its location, JIIT Noida is mostly preferred. Being closer to Delhi, it has access to nearby corporate houses and IT firms.
• Students get to attend seminars and industry visits quite often.

Quality of Education

• The faculty is much better at JIIT Noida. Being a private institution, it provides personality development and other exposures.
• Students tend to follow a routine and are disciplined.

Placements

• JIIT Noida is better than IET Lucknow in placements for sure.
• The CSE department is the best among others.
• The highest and the second-highest salary offered at JIIT Noida to the batch of 2016-20 are INR 43.17 LPA by Adobe and INR 34 LPA by DE Shaw.
• CSE is also the best branch at IET Lucknow.
• Students get placement offers from Microsoft with a salary of INR 37 LPA. However, on average it is decent.
• Bharat Electronics Limited (BEL) is a regular recruiter at IET Lucknow for ECE students.

Being a government-run college, IET has far fewer restrictions than JIIT Noida which appeals to many students. But it lacks in personality development and other exposures which you will get at JIIT Noida.

Now that you have known about both the colleges, I think you can clearly understand yourself and make a choice according to what you need.
