Let's see if I can remember how that was explained to me.
Tubular tubing is stronger then boxed tubing because it has a uniform shape that disperses the load evenly throughout the tube. With Box tubing its weakness and load focal points are the edges. Meaning the load is increase along the boxed edges.
Now both styles are really strong. If you want really strong SFC's with a lighter weight then mild steel go Chromoly.
Also 3 points are better then 2 point. I wish I would have gone 3 point, but I'm still happy with my 2 point UMI SFCs.

Good explanation. So the question is, has anyone ever had the boxed SFCs crack or break? Is the stronger tubular option really needed, or can the boxed option handle the stress adequately? I've had shop owners tell me that the regular steel is strong enough, that the chromoly is overkill as well, but I don't know enough to say myself...

I haven't seen anyone break either type unless they hit something bigger then the car. I think it comes down to what your taste are. Some ppl like Boxed in look, some like tubular.

I am very happy with the UMI tubular 2 point SFC's on our car. They are substantial pieces and tuck up under the body real nice.

I just wish you could order the darn things in plain bare steel. I want to paint them body color, and I hate trying to strip that pain in the arse powder coating off.

Are you saying the 3-point sfcs are easily noticeable from normal viewing angles?

I got mine in Black and you can't see them at all from the side. Red does stick out more.

It's body color for me or none at all. I want them to be invisible against the floor as much as possible.
