All the colleges you have mentioned are well known. Now while considering a college you need to consider some parameters:

• Curriculum
• Faculty
• Placements
• Infrastructure

Now as per my opinion you should choose VIT chennai because it has better lab infrastructure than SRM KTR. Also the VIT chennai faculties are highly experienced and the majority of the teachers are active in research but in case of SRM the research involvement is less. The placements rate at VIT CHENNAI is quite good (>90%) with average packages of Rs. 7-8 LPA. The most important part is that the curriculum is more well organized in VIT rather than SRM. This is the only reason why you should consider VIT over SRM.

Now as its your career and its the most important,  you should conduct a research by yourself and if you agree with my point of view then only rely on it else take the decision which will be the best for you according to yourself.
