It may not be right to compare the colleges under DU among each other. As most of them have similar curriculum and teaching techniques.
But if infrastructure is considered Deen Dayal Upadhyaya College (DDUC) is far better than other colleges under DU. As it is a newly established institution, the facilities provided are upgraded with the latest technology.
They also are known to have a very highly experienced faculty, some of them even having 20-30 years of teaching experience. DDUC is popular for its Science and Commerce streams.
Therefore if you wish to choose among DDUC and ARSD College for an Honours degree in Computer Science, it is suggested that you go for the former rather than the latter.
