It partly depends on the branch that you have considered taking admission in. Check whether the branch is good or not before deciding. Because if you are getting the branch of your choice in either of the colleges, then go for it. 

Now, when talking about which institute is better, then there are several parameters to decide upon. One of my friends decided to enroll in YMCA, Faridabad because for the following reasons stated below. Here is how she explains it,

• You will need a better rank to get selected for the same branch at YMCA Faridabad as compared to UIET Chandigarh. She obtained CE in UIET Chandigarh with a particular rank of 24024 in her first counseling. While in YMCA Faridabad, she got IT in her second counseling, and CE in her third. This itself speaks a lot about the situation.
• Besides, UIET is a department under PU, while YMCA is actually a university college under the same.
• Apart from several reasons stated above, Chandigarh can definitely be a good city to live in as opposed to Faridabad. That can be the only upside to it.
   

Hope these factors will help you in choosing what is best.
