I would recommend Aakash because they have being teaching students since very long time with nationwide pool of faculties. This allows Aakash toretrospect questions better and set a more near to NEET mock tests and test series.

Also it has a huge student base which allows you to compete nationally during AIATS that gives you a NEET like feeling. Dwarka Aakash is the main centre of Aakash and boosts some of the best faculty available in market.
