I take the "long view," back in the 1960's EVERYONE shot DuPont FFFg as that was the only black powder on the market-at least until the DuPont powder plant in Moosic, PA blew up! That is when importers suddenly replaced the DuPont powder on dealer's shelves with Curtis & Harvey black powder imported from Scotland.
Turned out that the Curtis & Harvey powder WAS BETTER than the DuPont black powder. As it turned out, just as soon as the DuPont factory was back in production, Curtis & Harvey powder disappeared from dealer's shelves again. We went back to DuPont being the ONLY black powder available. Somehow, I had a feeling that DuPont was maintaining a "monopoly" on supplies of black powder.
After DuPont got out of the black powder business-suddenly other black powders started appearing on the market. I recall seeing my first can of Schutzen black powder, "Made out of pharmaceutical grade ingredients" in the early 1990's. Then more and more brands of black powder began showing up on the market.
That has spawned a "competition of sorts" because now ALL the manufacturers are producing better, higher quality, powders. When KIK powder first came out, I tried a can of it-and it was horrible-barely "firecracker grade" black powder.
Now KIK powder has improved to the point that it is starting to rival Swiss black powder (the "Gold Standard" of modern black powder.)
The owners of the Elephant plant down in Brazil had hired some American experts and Elephant was in the process of improving their products when the family that owned the company decided to sell the plant. The plant was purchased by another group of Brazilian investors and now the Elephant brand has been replaced with the Diamondback brand manufactured in the improved and upgraded old Elephant plant.
My point? Well, back in the mid-19th Century high quality English black powders were the best in the world. Curtis & Harvey developed a super grade black powder that could ONLY be used in Martini-Henry ammunition. As the Martini-Henry was the service arm of the British army, the British government FORCED Curtis & Harvey to give up their trade secrets of making their superior grade black powder in the interest of "National Defense!"
So, I am very glad to see that Goex is coming out with a high quality powder. I have a feeling that in a few years we are going to get some black powders on the market that are equal to the old Curtis & Harvery and the other high quality British black powders of the 19th Century!!
As for the "substitute" black powders. I have a friend who will occasionally drop by and give me a pound of Pyrodex or one of the other "substitute" black powders. I have a good use for them: I scatter those substitute black powders on my garden as they seem to be excellent fertilizers.
To paraphrase the old Coke slogan: "There is nothing like the REAL THING!"
