The Herbie works just fine for most, and is what I am setting up on my Aqueon 75g RR, but, the emergency line on a Herbie has to purge itself of air before it can flow full volume. For most of us, that is on the edge of flood as most of our emerg lines are high and small.
All the Bean does is place the secondary at the same height of the main, so it's less prone to floods. Then you still have an emerg as well. And all 3 are large pipe.
Plus, the Bean is self-adjusting, and our Herb's aren't fully auto.
