Hello Dear,

CA, CS or ICWA is considered as one of most prestigious examination in India.  Both the institute are good but it depends on you how you conceive and gel up with the teachers. The faculties are very experience and knowledgeable. But I will recommend you  J. K. Shah classes. The conceptual teaching and portion completion at J. K. Shah Classes is great. The test series gives a complete practice of real exam scenario and scope to improve in final exams.

Good Luck
