CU is known for competitive placement records and strong industry tie-ups, especially in recent years. It has good coding culture and decent exposure to tech companies.
On the other hand, LPU offers a larger campus ecosystem, more CSE specializations (AI, Data Science, Cyber Security, Cloud, etc.), and a wider recruiter base visiting the campus. The placement training structure at LPU is also well organized.
Overall, if you want slightly broader exposure and specialisation flexibility, LPU may have a small edge.
