Thanks for asking this i want to tell you that selecting among these colleges for admission depends upon various factor like following.

-Location

-Minority/Quota

-Course of interest

Firstly,As you have shown interest of taking IT, I would say go for SPIT not because it is more reputed than any other mentioned colleges but the plethora of placement opportunities you get here is very complacency and being student of SPIT, I personally have experienced it and due to it’s recent tag on Autonomous college got more attention for the admissions and SPIT is considered maharashtra’s 2nd top best college for engineering if you get CS its good as well . Secondly, talking about its location you have various advantages if you are western zone (Railway) traveller it also does not take much time to reach from Andheri station. Though KJ somaiya is also better one but this college got Gujarati minority so if you belong to that you can go for it definetly since chances are more. I can’t say much about DJ Sanghvi but few of my friends study there and they are happy about it as per there convenient..so, lastly i want to say don’t just go with advises of others take your own time as per the mentioned factors you will be happy with your choice.
