Sub Frame connector conundrum

Your logic is not accurate in my opinion. Have you tried to twist a box tube? I have not. I can only imagine what it would be like. There are 4 parallel walls all intersecting at a right angle w/o seams. Now you connect two of these box tubes from the rear frame rails to the front and you you have 8 walls and 8 90 degree seamless intersections. The torsional rigidity is proportional to the strength of the box tubing. The separate box tubing running parallel to the floor board yields 2 more walls for strength than the units which are laser cut and welded to the floor. The box tubing is considerably thicker. Using your similar logic one could perceive that the advantage in tying the frame connectors to the floor is mainly not in torsional strength but in the bow and bend of the mid section on an axis across the middle of the floor boards. This is also moot since the roof structure, the floor structure and a box tube sub frame connector all combat bow as well.

In summation, I would use the non scientific modeling process to say that the walls of box tube sub frame connectors are thicker, seamlessly intersected at 90 degrees and also increase the number of walls by 2, so would be much stronger. There is no possible way to prove which ones are better w/o measuring torque applied to different sections of the body while the body is on a jig w/ measurement equipment all over it.
