Having known some people studying in both these colleges, I can share some information about them. This might help you make a decision.

Student Crowd:

• During the 90s, YMCA was very popular and a lot of good students used to get admitted here.
• Nowadays DCRUST enjoys a better student crowd, as many students from NCR are also getting admission here.

College Life: 

• DCRUST takes the lead here. If you prefer extracurricular activities, it is the right place for you.
• They have activity clubs, literary events, social welfare clubs, and also a drama club called Sparsh.
• These activities will help you groom your personality.

Hostels: 

• DCRUST is known to have better hostel facilities than YMCA.
• Also, it is famous for Murthal Dhabas.

Placements:

• YMCA tops this, as they have better placement opportunities than DCRUST.
• A lot of notable companies participate in their placement program.

Both the colleges are more or less good to pursue your studies. Though it is suggested that if placements are your primary concern, go for YMCA. DCRUST will help you more with research-based knowledge.
