There's three important differences. Their approach uses the diagonal tension lines to move the wave energy down to the seafloor, you approach shifts it to another spar. They have steel (or whatever metal) as guy lines in tension, you have substancial metal braces between the spars in alternate tension and compression. Their approach is fairly unrestrictive to boats, but your horizontal top connectors impede boat traffic. You must have adequate floatation somewhere to hold up the horizontals.
I suspect they will have many snapped guy lines after a storm, and your system will be intact. As for boat traffic, i say "somebody build both and lets see how they function in real life!".
I admit that previously, i did not realise the triangular structures in your drawings laid flat at the surface.
