NIRMA is good compared to DDU. The placements are also very good at Nirma compared to DDU.  The reason being the brand image of the university, the faculites teaching and also the way the course curriculum is decided. Also, the seniors at the college are very supportive for any kind of help. And there are events round the year which keep the campus lively and also help you to learn the so-important-in-today's-time soft skills. So, I suggest Nirma.
