I have a friend studying at IET Lucknow from the Civil branch. I will not be able to tell you about HBTI but I can guide you in the case of IET.

• The mechanical branch of IET is the best in the entire college in terms of studies.
• The faculty of the mechanical department is the best and you would not regret pursuing B. Tech in mechanical engineering from IET Lucknow. The faculty teaches better than what the students are taught in coachings (as per mechanical students).
• But as far as placement is considered, it is almost nil. The only companies that visit are from the IT sector. Even if a core company visits (rare chance), just a few students get placed. So, I would recommend you not to join IET if your parameters are good placements.
• Considering the college tag, HBTI is a renowned college but IET is also not unfamiliar. IET is well known among IIT professors.

The following table shows the placement statistics of both institutions:

Being from IET is also not bad, though not comparable to being from Harcourt.

Having friends in these institutions, I am well aware that HBTU Kanpur is much better than IIIT Bhopal and IET Lucknow. Though one thing has been seen that the performance of the CSE department is generally the same in all the colleges. They all provide enough industry exposure to the students. 

This table might help you in seeing the basic differences between these institutions - 

It is advised to join HBTU Kanpur or IET Lucknow than IIIT Bhopal, as the former are an older establishment than the latter which is comparatively new. Classes at IIIT Bhopal are scheduled according to MANIT Bhopal. Also the students are provided RGPV hostels. So it will be better if you go for HBTU.

Having talked to people at NIT Raipur and HBTU Kanpur, I have gathered reasons why students should opt for NIT Raipur instead of HBTU Kanpur for B.Tech. 

These are described below - 

• NIT has a brand value as it has a renowned name and fame, which will benefit you in many ways.
• There is a more competitive environment in NIT if compared to HTBU.
• There are more technical, cultural, and sports events in NIT than HTBU which helps the student to develop their personality and intelligence.
• NIT is a government-funded college so more funds are given to NITs, which help them to provide more facilities to the students like Advance labs and classes.
• The alumni reach of NIT is more than HBTU.
• The average placement of NIT Raipur is better than the HBTU. 
• Students can avail 100% fee waiver if the students have low family income.

The table shows a brief overview of the institutions:

Overall, NIT Raipur is the potential choice for B.Tech rather than HBTU Kanpur. Even students of HBTU also prefer NIT Raipur over their college.

After going through the reviews online, I would like to mention that both the institutions are good in their own ways. Here are some things I got to know from the reviews of both the colleges.

• The facilities provided by Heritage Institute of Technology are very good. 
• The teaching and non-teaching staff is excellent and the institute has a library that is well equipped.
• The alumni network of Heritage is strong and they will help you a lot when it comes to research.
• The placement cell of Heritage is also brimming with activity. 
• The engineering departments are under the leadership of the principal who used to be associated with foreign universities.
• Also, in the placement season of 2020, the CSE department of HBTU enjoyed the most success. 
• Most of the students who ended up getting placed belonged to the CSE department.

Therefore, you can choose any of the colleges to study, as they are both equally good, so studying in any of them will be a great push forward to your career.

HBTU and IET Lucknow both are government colleges and are considered to be tier 3 colleges whereas JSS Noida is a private institute and is considered a Tier 4 college. Normally tier 3 is favored upon tier 4 but in this case, JSS Noida is a very fine institute as of now both in terms of academics and placements.

• Private colleges like JSS Noida offer better opportunities and facilities than government institutes. 
• The placement HBTU and IET Lucknow are the same as JSS Noida. 
• Students from the CSE branch of JSS Noida get into well-based companies and MNCs and are offered packages far better than that of HBTU and IET Lucknow. 
• Normally students from HBTU and IET Lucknow get offered packages worth around 8-10 LPA. 
• This is the same with JSS Noida for other engineering courses but for CSE the packages reach up to 25 LPA.
• Students from Chemical engineering are not employed by any core companies in India as they are very few. 

CSE branch has more value than any other engineering branch. The best option would be CSE from JSS Noida rather than Chemical engineering from HBTU or other engineering branches from IET Lucknow.
