Yes, there is no doubt that VIT is more preferred over Vellore, as it is their main campus. They actually have an advantage that Bengaluru is the largest Technological hub of India, so they have a great location advantage, and they have a very good faculty base, as I was told by a relative of mine who studied there. So, I would recommend to go for VIT-Vellore.
