Hey 

VMC delhi used to offer only Jee / Advanced coaching to engineering aspirants they have started with medical coaching some time back only 

on the other hand Aakash offers both engineering & Medical coaching 

from reviews 

VMC has been better for Engineering & Aakash has been good for Medical 

I did my coaching from Aakash (2 year programme)  & the study material for NEET is actually good plus the notes are good too 

so it’s on you to decide.

good luck!
