Among the colleges mentioned it will be better if you go for Atma Ram Sanatan Dharma college. 

• It is better in terms of connectivity, crowd and extracurriculars.
• Academically, it depends on what course you are willing to opt for. 
• Atma Ram is the best among them. It is the best in Arts, Science and Commerce.

Here is how your preference should be. At first it is Atma Ram, followed by Deshbandhu College. If you are not able to get admission in both of these, then opt for Keshav Mahavidyalaya or Rajdhani College.

One of my friends recently graduated from Delhi University. According to him, the college does not matter much as long as you are onboard with the courses you choose to study.

Among the given choices, studying in Rajdhani College or Motilal Nehru College does not matter, because as students you have to put your own effort in building your career. The institute can only provide the required guidance, so the rest is up to you.

So choose the one that is more convenient to you in terms of accommodation, locality, crowd, communication, etc. As both are under DU there will hardly be any major difference in the curriculum.

Among all these above mentioned colleges it is recommended you go for Motilal Nehru College. 

• They have a highly experienced faculty.
• It is located in South Campus. 
• There are proper facilities for transportation and accommodation available nearby.
• There are many societies and clubs which you can join according to your interests.

Opting for MotiLal Nehru College will be better due to its south campus brand value also the provide numerous opportunities to the students both professional and extracurriculars. Though the ambience of that college is a bit inclined towards politics, still it will prove to be better than Rajdhani and Ram Lal Anand college.
