I would go for VMMC Delhi. The reason being patient load. Delhi being the capital, people flock from peripheral states. They try for RP Centre, AIIMS but due to huge patient burden all patients do not get chance of treatment and hence more to other Delhi colleges. During PG, getting huge number of cases both rare and interesting is a key point of study, research and paper presentation thesis etc. 

BJ Medical College shall mostly get patients from Gujarat whereas Delhi being capital will get patients as far as Bihar and J&K.
