One of my friends studied at Ramjas College, so my answer might be a bit inclined towards it. But SVC is also a good institution, so the choice basically depends on that particular individual.

• Ramjas is located in the North campus while SVC is in the South campus.
• Ramjas is known to have the best faculty for Botany at Delhi University. They have a dedicated greenhouse for botany students in Ramjas.
• Both SVC and Ramjas have really good lab facilities. 
• ECA participation is almost the same in both colleges. 
• Ramjas has its own Model United Nations society, which SVC does not. 
• Also, Enactus Ramjas, which has been second in the nationals for 2 consecutive years, is far better than its SVC counterpart.

So, it all comes down to the fact where you want to live, grow and explore. Choose the one that suits your requirements the best.
