I would say that which ever coaching gives extensive  study material and  a lot of practice modules  is fine. I cracked my jee with akash  coaching material. See all standard coaching  design their modules in such a way that all concepts are covered. So my recommendation is which ever you choose learn it throughly before moving for other coachings modules.

Students think that learning one chapter form one module and other from other is good. But it will never help a lot. You should practice different problems but sincerely follow one.

In my case 1-2questions were direct examples from akash modules in jee advance2017
