I am not sure on Bandwidth, but BBB does integrate with other learning platfors such as Moodle
https://bigbluebutton.org/schools/
So would you need to take this in to account also if calculating bandwidth use.
BBB is far more polished, so i am guessing they have worked out a way to keep bandwidth use as efficient as possible.
