It’s like u r asking if stainless steel is costlier than platinum lol.
RV stands great, Karnataka’s no.1 engineering college. You should rank within 500 in kcet to get computer science in RV whereas u can get in presidency even if ur kcet rank is more than 50000.
Placements:Average salary one gets after graduation is around 7lpa. In presidency it very difficult to get placed in campus no matter wt the pakage is offered.
Conclusion, RV is incomparable to presidency.
