See both the courses have very good job scenario in India. If you wish to go for a job with more salary then pursuing the course of Operation Theatre Technology will be a better choice. The salary increases, as the OT technologist needs to work in extra hours and may also be in different shifts. As a result, the salary increases due to this case.

Both of the courses are great, in some hospitals such as Apollo, the salary for both the technologist are quite same but from a general perspective, OT technologist earns more due to there over shifts & rigorous time laps schedule.
