Which engineering stream is better amongst agricultural, mechanical and electrical?

Don't choose best field. Choose that field in which you are really interested in.

All three of the street are best in their sector only you have to choose which of it you have interest it's all depends on the interest BN that's all.

Hi, best depends on you interest not a general criteria. So, you should go for the one you think good enough for you and interests you the most. Thanks.
