Doing an M.Tech in EC is better at JNTUH. Though Osmania University is an old institution with a history of more than 100 years, it lacks in PG and Ph.D. courses.

JNTUH on the contrary has a good reputation along with great infrastructure and strict guidelines in terms of the faculty members. The university cross-checks the background of each faculty member who will be teaching the students every year.

In terms of curriculum, JNTUH follows the latest syllabus and has a strict attendance system. It has a biometric attendance system and you can be detained if you have less than 75% attendance. If you are looking forward for higher education in engineering, go for JNTUH.
