Oh I have no idea how it compairs.... Where I live one can buy clones from almost anyone so when I need cuts for a run I just ask for whatever it is I want and someone knows someone who has it. While people do differentiate between headbands, ie. 707, 818, and reg, or OG, ie. sfv, sky walker, etc. the sd is always just the sd. I have definitely had some that produced better or smelled stronger but I couldn't tell you which was which. Sorry M8!
