Out of these two, Dayanand Sagar is definitely a better choice because it is an autonomous institute. However, you will encounter multiple distractions on the campus and it is advisable to be cognizant and not to neglect studies.

Dayanand Sagar has a good reputation in terms of co-curricular activities. One of my friends, who got RNSIT in the first round, waited and later opted for DSCE in 2nd round.

Trust me it was one of the life-changing decisions in his life. Rest is up to you, do whatever you feel like.
