Hello student,

Every IIT has it's own advantage and disadvantage.  According to me IIT Kottayam is better than IIT surat at ECE . IIT surat was established in 2017. IIT Kottayam was established in 2015. They follow the course and carriculam like Hyderabad IIT. They put many efforts in academics. Student teacher interactions play an important role in our life to grow,which is also excellent. The it has got quite good placement records compare to IIT surat.

However, this is my personal opinion.

Hope it helps
