Hi Sachin,  

Preference list order may be like this 

1.Christ 

2.Amity NOIDA

3. ICFAI

If you are from outskirts of Delhi or from Delhi,  Amity NOIDA should be preferred. If distance is not the barrier than Christ University should be preferred over Amity. Christ Bangalore has a really good track record and the timings of the college are very flexible and one can even pursue internships alongside college which will not be possible at Amity NOIDA.
