The initial DB Super episodes were dumb, and then then stuff based on the movies was kind of bad animation-wise. I think they may have cleaned some things up for the BD releases.
I stopped after a few episodes, waited for the stuff covered in the movies to finish, then started watching. I don't think there's much of anything that makes watching the same stories get stretched out in episode format worth bothering with, so IMO I'd just watch the movies, jump onto the arc that starts after them (I think it's universe six?), then watch the Broly movie.
