Hello Paramveer,
I think CSE in Chitkara University is far better than metallurgical engineering from PEC. CSE has become one of the fastest growing and most popular programs worldwide. There are numerous job opportunities in CSE, that's why It's considered one of the most high-paying jobs in a current industry. Chitkara has a good reputation for its engineering programs.

Chitkara is better for B.Tech in CSE as per its academic reputation and industry exposures, It has been ranked as one of the best private university by various factors on the basis of its infrastructure, pedagogy, faculty and more important its placements concerns.

CU is a better option over RBU for BBA as it has little better brand value.

Shimla University is best because it is an international university and you will get good exposure.

Chitkara University is well known for IT and engineering courses.

NIT, Hamirpur is better for MBA as it has better reputation than the Himachal Pradesh University. I cannot give information on the placements because the current batch is the first batch of MBA from NIT-H, and no companies have arrived yet.
