I ordered a couple of pounds of Graf FFFg along with a couple of goex FFg and have been shooting them side by side for comparison. In my .54 GPR, a 95 grn charge of the goex shoots to the same POI as an 85 grn charge of the graf with same ball/patch combo. I had heard the the graf might be dirtier, but my observation was exactly the opposite. Shooting the goex, at even a lighter charge, I'd get 3 shots before I needed to wipe. At the 95 grain charge, I could load the second shot with difficulty, and have to wipe the bore every other shot. Suprisingly, with the Graf powder in FFFg, I could put together an 8 to 10 shot string before swabbing the bore. MUCH easier loading , and the damp patch would come out with less residue than the goex patch would after only a couple of shots. Plus, it's cheaper. My experience only, YMMV.
