Heritage Institute of Technology would be a better choice. Since it has become autonomous, it has advantages over institutes that are under WBUT.

• Heritage will provide you very good exposures in both from the academic and the industrial point of view. 
• You will also be aided in your research and project oriented internships from the faculty. 
• It is one of the best institutes for pursuing engineering not only in Kolkata but in West Bengal. 
• The environment of HIT is also excellent for studies.

A lot of my friends studied there and they are very satisfied with the education and training they received. So it is suggested that you go for Heritage Institute of Technology.

The B.Tech programs offered by CU are far superior to Heritage in almost every parameter. 

Student Crowd:(CU>HIT)

Going by the recent cutoff trends, the closing rank for CSE at HIT is around 3.5k, whereas for CU it is around 1.1k. Many students from HIT CSE in fact shift to CU Chemical, Electrical, Instrumental during the spot rounds. 

Faculty Base: (CU>HIT)

• For branches like CSE/IT, CU has a great faculty base. There are faculties like Amlan C & Nabendu Chaki who are from Ivy League colleges. In fact, most faculties of CU did their Ph.D., Post Doc from reputed universities abroad or from institutes like ISI Kolkata, SINP, JU, etc. 
• Whereas, most faculties of HIT are CU alumni. The majority of them just did their M.Tech and started teaching. 

Reputation: (CU>HIT)

CU is consistently ranked in the top 10 by NIRF. It also has a good ranking in Asia as well as the world. SN Bose, APC Ray, MN Saha are a few from the vast list of world-renowned alumni of CU.

Outcome: (CU>HIT)

• CU has a graduation rate of around 91% which is much higher than most universities in the country including JU. The graduation outcome for Heritage is around 51%. 
• Also, research paper citation (RPI), public perception, teaching & learning resources of CU is far ahead of HIT. 
• The median CTC offered at CU is around 6 LPA. For HIT the median CTC offered is around 3.35 LPA. 

Infrastructure: (CU>HIT)

• CU offers classrooms equipped with modern facilities and air-conditioned labs. The course fee charged for the B.Tech program is 30,000, which is quite less compared to HIT. 
• HIT Campus is bigger than the technology campus of CU. However, most of the HIT campus area is occupied by other departments such as management, school, etc. 

Judging by all these factors I will say CU is definitely a better option than HIT.
