My sister studied computer engineering at DDU. Based on her experience I will recommend you to join DDU. Here are the reasons why you should choose DDU. 

• DDU CSE department is way older than PDPU. As a department, it has more experience. It has also improved a lot over the years. 
• The faculty members are well-educated and highly experienced.
• The laboratories are well-facilitated.
• From 4th sam, you will have to do projects. That way you will get to learn about real-life projects.
• The placement record for DDU is also quite good. The placement average is around 95%. 

So, overall DDU Computer Science will be a great option.
