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.
