First of all congratulations to getting decent rank so you are able to join these college.

Now comparing these two college i will say CSE in NIT bhopal is far better than IT in IIT allahabad in terms of placement . But if you are keen interested in coding then you will find better coding environment in IIT Allahabad. Both college are equally good and hold its own importance in their own field.
