According to me, heritage institute of tecjntechn is best in comparison with salt lake cause the heritage is provide good facility with great academics and good placement. The average package is around 3.5 lakhs per annum from heritage college. So it is best option. also from past passed student review this college is great and good suited for you
both are affiliated to maulana abul kalam azad university of technology. heritage is slightly better than techno.
