Bergger warmtone Graded vs VC.

Has anyone done a side by side comparison of the graded and vc versions of Bergger's fb warmtone papers. I usually prefer graded papers for sharpness and image depth but recently printed with some of the vccb paper in 130 developer and it was certainly sharper than most vc papers I have tried. So my question is if there is a noticable difference between the graded and vc warmtone papers? If so is the difference in relation to image tone, warmth or sharpness etc.

thanks,

Matt
