Hi Naveen,
I actually don't know about the other two colleges, but what I can say is St. Xavier's College, Kolkata is really an outstanding college. You can see it in the NAAC ranking also. We topped the list with 3.77 out of 4. And this is the highest score ever.
So, I would say this is the best college in India.
All the best.

Yes, but it totally depends on your experience, percentage and skill.

CLAT result is amazing. IMS is also good.

Overall it is a good college. Faculty are good, but the main concern is placement. So, I will talk about placement more
Placement cell was good during my college tenure. Placement was done on a rotation basis. Though I did not get any placement at the end of the course, 20% of the total student got placement that year. The jobs offered were not so good and the salary was like stipend. I got a job in a renowned hospital through my personal capabilities. I think the job placement cell did a bias work that time.
