Hi there!!! Which branch to choose is really dependent on your interest. I am myself a student of SVNIT and trust me its a great college in every aspect. You should choose branch of your liking only since it will bring out the best in you and SVNIT is one such college which is full of opportunities and will surely bring out the best in you. Still if you insist on the better branch of SVNIT then I would suggest mechanical, comps or civil. These branches have the best faculty of SVNIT especially mechanical. But ultimately its your level of interest that should be the deciding factor. Hope this helps. Wish you all the best.
