Hello yash

Hope you’re doing well

Look, both these colleges have pros and cons but still Chandigarh university would be better to pursue CSE.
the college life at Chandigarh university is very pleasant.
the placement record and the packages are much better than at sharda university. Living in Chandigarh is itself a great experience. They have excellent placements and variety of co curricular activities too. Faculty and staff is very helpful and kind. You can surely go for it.

All the best:)
