Hi Sai,

Hope you're doing well.
All the campuses of Amrita University are good but among all of them the Coimbatore campus is the best in terms of infrastructure and also campus life.

It is always advisable that before choosing college you choose the engineering branch that appeals to you the most. That is do not think of campus but select based on whether you like ECE or CSE.

However, if you do not have any preference as such, it is recommended that you go with the Coimbatore campus.

Hope this helps.
