Honestly, this is not even a comparison. VIT (any campus) is way better than Heritage Institute of Technology. Actually, Heritage Institute of Technology is not even the best college in the Kolkata region. It is the Institute of Engineering and Management (IEM).
Heritage Institute of Technology is obviously cheaper than VIT to study and also closer to your home if you are from the eastern region of India. You will get a job after graduating with a starting salary of around INR 3.5 lakhs per annum. If you have financial constraints and you are ok with this kind of starting salary then Heritage Institute of Technology will not disappoint you.
However, if you are well enough to pay for the fee of VIT, then in no way you should even think of Heritage Institute of Technology. The environment you will get there are obviously the placements of VIT are way better than Heritage Institute of Technology to even consider them for comparison.
