Hi, both the colleges are equally good but the science faculty of Acharya Narendra Dev is quite well known. The college might not be great in terms of infrastructure but on academic front it is. The college has Grade A accreditation from NAAC. Deen Dayal Upadhya college has good faculty(Grade B accreditation from NAAC) as well as good infrastructure. 

You can further compare both the colleges from here: https://www.careers360.com/compare-colleges?college=51823-47584-course=152865-152968-compareresult

If you get Acharya Narendra Dev in the next or further cut off lists, you can go for it.

Good Luck
