It's great that you chose two best options, now if you analyse IIIT Jabalpur, the placements are really very good. The salary packages offered by the companies range from 7-9 LPA. Electronics and Communication Engineering is taught by experienced faculties, this college is overall a great choice. Now JNTU Hyderabad is going to offer you better campus life, well equipped labs and wide range of facilities but the placements of the former one is better. Consider all of these aspects then choose.

Good luck !!! Get detailed brochure of both the colleges
