Strength between c-channel and square tubing

Is this for an industrial or commercial setting? If so, you should not be the one making the decision. It is such a naive question that it shows that you are nowhere near qualified enough. No offense, I hope - just trying to keep you out of trouble.

Vertical or horizontal installation? formed channel or extruded? aluminum or steel? what alloy? what kind of load? static or cyclic? What thickness?

All elase being equal I would say 2.4 inch tubing, but seldome in these kinds of questions is "all else equal", or the question would not need to be even considered, much less asked, as the answer is SO obvious.

The strength and stiffness of steel is beyond most peoples' experience so they have no basis to estimate it.

Devoid of any idea what 'load' is intended, what joint construction and bracing methods, what material, and what environment, I'd say they are both more suitable. So is bamboo, concrete, and titanium forgings.

Celery stalks, however, suffer structurally in the "dryer" environment.
