Every college has some pros and cons and eventually it is the student who matters.
Yet I would say that VIT Chennai may be somewhat better in terms of exposure, alumni base, proximity to head institution, etc. VIT Chennai was established back in 2010, so atleast a decade has passed since its operation. So they would have secured better contacts with companies and they will have more experience in handling issues.
Yet take some information from someone who has been there, someone who can provide an insider view. Only after that take any step.
Good luck!
