Depends on the load. If I can break the 75lbs up into two equal loads than using my Big Dummy or the CETMA is pretty much a draw. If the load can't be split - say 1 big box the CETMA wins for sure as I can load it centered on the platform. The CETMA also wins for a loose load as I can simply dump it into the box and ride off with no hassles. The BD requires lashing down of every load and a loose load needs to be bagged or boxed or it won't work.

OTOH I prefer riding my BD unloaded. I never ride the CETMA for a non-cargo run.

BTW - I don't have kids, but if you have a small child or a dog! the CETMA is a superior rig to keep an eye on them and interact with them. My close friends are having a baby and I'll be loaning them the CETMA for a while when they want to start biking with it.

If you wanted an analogy...the CETMA is a 1 ton dually pickup truck and the Big Dummy is a Ford Ranger 1/4 ton.
