As aiims is a central government running institue and also the serene beauty of risikhesh alot of good faculty are willing to join here so aiims risikhesh will have more good staff than pgims rohtak.At aiims they give alot importance to medical students so no doubt you will pass out with plenty of skills and knowledge.However pgims ranks above aiims risikhesh but the less fees at aiims is a good decision.Anyways at the end dont rely on others opinion do research for yourself before coming to a decision.

All the best !
