Honestly, it is a lot about personal preference. They are both high quality kits.
I'd prefer the SOS due to the mounting location though. That is the largest difference in my eyes and I'd prefer to preserve space inside the car at all costs so SOS is the clear choice for me.

The 2006-2009 Honda S2K is a perfect candidate for our new FST-R.

Installation would be easy.
Simply connect the OEM Fuel Tank hose to the side port outlet of the FST-R with a -6AN hose.
Connect a -6AN hose from one of the FST-R ports to the OEM Fuel Tank.
Using this billet coupler adapter

install it inline with your large fuel filler hose and run the last -6AN hose from this billet coupler adapter to the last FST-R port.
This would automatically convert the 06-09 returnless fuel system to a traditional return type without touching the engine bay.

I dont see how the Radium tank would convert a MY06 to a traditional return style system. You need a return line from the rail and a FPR at the rail itself.
Having returns going from the surge tank to the fuel tank (via fill hose) does not make it a traditional return style system.
