Hello aspirant.

Both of the above mentioned B.tech course is good in Vellore Institute of technology. So, you can go with your interest in any of the above mentioned courses.

However, according to my opinion, You must prefer CSE (Computer science and Engineering ) over ECE (Electronics and Communication Engineering) in VIT vellore, because the CSE branch has more scope as compared to ECE and more job opportunities as well. It has higher salary package as well. So, you can go with CSE branch.

Further, to know more about the CSE in VIT Vellore, all other details, you can follow the below mentioned link to know more about it : https://www.careers360.com/university/vellore-institute-of-technology-vellore
