Hello, both are good colleges and since, you have mentioned your two options.
In my opinion Nit Patna is a good choice as it is a Nit and a highly reputed college.
Placements are good and you will have good opportunity for placements and higher studies.

If you are interested in computer science engineering then you can go with RV college.
It's depends on your interest and for which branch you will do better.
