Hi aspirant,

All the colleges mentioned by you the leading private Engineering colleges of India. Out of these Vellore Institute of Technology is the best with Amrita Vishwa Vidyapeetham just behind it. Vellore Institute of Technology is the highest ranked private Engineering College of India followed by Amrita University and both colleges are known for its amazing placements, infrastructure and the environment it provides to the students. Following this MIT comes the next with very good placement opportunities but it is is costly in terms of academic fee. SRM institute of science and technology comes next in the list with the main campus in Chennai being one of the most reputed institution in the country. Kalinga Institute of industrial technology is at the same level with SRM but only thing is it is better known for Computer Science and Engineering only.

Rest of the colleges mentioned by you are still growing and can be considered at same level and you can choose among them as per your wish and convenience but tech Mahindra edges slightly over others.

Hope it helps!
