Hi there,
If you talk about best thenVIT is 100% better among all of the above. VIT is much better in terms of acadmics, infrastructure, placements etc.
Manipal, Kiit, Cu, Srm these are also very good college but not as good as Vit.
Secondly to get admission in the above college, you have to clear jee mains with a very decent marks of more than 93+ Percentile for general category for most of them.
Although they have their separate exams as well like
But jee mains marks are also considered.
Now every exam is equally difficult to clear.
I hope this helps
