Conditioner internals: Bus bars Vs. Wiring? Ala, P20

I was wondering what the consensus is on high end power conditioners that connect the outlets with solid OCC copper bus bars rather than wiring? There is a reason I find this of interest. You will find this in some of the highest end conditioners. It is also exactly what is to be commonplace in $5 surge strips!

Edit: It had skipped my mind that the P20 of which I own two of utilize these bus bars.
