See curriculum wise, the theory portions of MA education can exceed the knowledge of B.Ed. But the MA education don't get that much of a exposure in the teaching sector as compared to B.Ed. This is the reason why despite of your MA in Education the B.Ed will be preferred more in teaching sector due to this exposure and certification of teaching. Also, the government has specified it to be mandatory for teaching jobs in Government schools as well as some private schools also require the degree as the eligibility.

I hope my answer helps. All the very best for your future endeavors!
