Dear aspirant,
I would undoubtedly choose nit Warangal or nit surathkal computer science branch as iit Ropar definitely comes under the premier institute brand name IIT but as it is a newer iit and cannot be compared to nit surathkal or warangal.
It's not like this that iit Ropar is bad in placements but if we compare to the iit brand it is not like what an iit should be.
The placements at warangal or surathkal are very good. The average package of these colleges in computer science branch stays between 18-20L. In case of IIT Ropar the placements is not upto the mark. The average stays between 14-15L.
