I have had the opportunity to see this question raised on many fronts over many years. Fifteen to twenty years ago, I would have agreed with Zulak. At that time, the BS curricula were rigorous enough to provide challenge and demanding enough to produce higher competence.
Both the curricula and the profession have been "watered down", not surprisingly for the same reasons, but from different perspectives. In academia, there was a push to create and further the ASCE philosophy, as well as deal with budget constraints that limited the coursework at the BS level. Further, there was a "dumbing down" of engineering coursework to comply with other University curricula norms (Why should engineering require more credit hours for a BS than an elementary teacher?...was the unknowing question asked by many administrators who controlled the budgets and thus the direction of many programs! As practicing engineers, we all know the answer to that, but it was obvious that they did not!)
In "industry" the enhanced marketing of credentials has become so important to winning projects that having a Master's degree (surprisingly, in almost any subject, as long as you have the BS in the appropriate one)has become very important. Insight is perhaps the most important product of graduate work. The coursework is not tremendously more rigorous, just different in its focus and perspective.
In short, any knowledge gained is beneficial and completion of graduate coursework is, fortunately or unfortunately, the verification of this gained knowledge.
Go for it!
