I might as well share my recent experiment.
I'd been running a beckett on my 180 for about 2 yrs using a MAK4. It performed great. I recently decided to put a second skimmer on system - so I bought a downdraft skimmer (I'm not mentioning any names). I installed the downdraft and retained the beckett on the system. After the downdraft was broken in, the becket shut down. I kept them both on line for a couple of weeks - becket never foamed up again.
This could be for many different reasons. But, fact is, the downdraft is more efficient than the beckett when comparing the two models I have. Both are rated for close to the same system sizes.
Just thought this was interesting......
