Never tried the Schuyler skunk or the FFX 4way but we had the VB ghani clone starting in mid nineties for many years along with a wicked origional old AK47 from serious seeds and a NL5 hybrid we created that was super fire . The VBghani grew big huge plants indoors and did well outside also. It is still to this day the strongest Indica we ever tried and we’re talking in 40 years of hunting, unreal expansion. She was a spider mite magnet when we got her , came in a cube of rockwool for 20$ . He actually gave us 2 of em for 20$ a piece. The 90’s were the pinnacle for ganga in our opinion, , todays weed is all the same with flavor and canibanoids bred out for potency. But the weed is no more potent now if not less potent . The highs are bland and one dementional. . The VB ghani was vigorous and never really got rid of the mites but she just powered through them . We trashed her (regrettfully ) because of the mites .. She is still talked about and around VB but held tight because the man who created it got broken into and ripped years ago at his grow. She is still around but hard to get . He had a nasty Super skunk and another hybrid we never got to try. I always wondered if that Super skunk was the one used by chemdog and crew for the sour deisel .. A lot of great weed on tour with the Dead . Wouldnt be surprised if its the same.
