I have friends from both Vidyalankar Institute of Technology and KJ Somaiya. Based on the conversations I had with them, I will suggest you choose KJ Somaiya for a CS degree.

Here are some of the reasons why you should prefer KJ CE/IT over Vidyalankar CE /IT.

• KJ Somaiya is an autonomous institute. So their course curriculum is quite flexible. 
• Vacations will be quite long. You can utilize this time to do internships in some IT firms. 
• The CS and IT department of KJ Somaiya has amazing CSI and other councils working for them. 
• KJ Somaiya has a vast campus. The sports facilities offered at the institute are also quite great. 
• The placement average for KJSCE is 100% for CS IT branches. As it is an autonomous institute more recruiting companies visit the institute for placements. 

Vidyalankar is not a bad choice either. Both colleges have their own advantages. Here is a brief comparison of the two institutes. 

You should do your own research on the institute and choose according to your convenience.
