Hi Ashwin,

Both BHU and JAMIA are good but i think you should prefer bhu. The law faculty of BHU is very reputated and much better. Also the infrasturcture in all green in BHU. Placement in BHU are very good and other than studies non acadmic activities also take place. On the other hand JAmia is not bad, if you take admission there than yu will be able to find diffrent people from diffrent backgroud. 

Basically both collees conduct entrance exam for admission and its totally on you and your interest that in which college you wanted to take admission.

All the best for your future.
