I have used both and don't see much difference between the two.If used too strong,IMHO, gives the product an off taste,more so notable in the brisket.
Main benefit is to keep a product that has been sliced or pulled from drying out after it has set 15-20 minutes in a competition turn in box.
I see David(Butcher's BBQ) at half of dozen contest's a year. Always go up and talk with him after judging is done. He is more than happy to answer any of my questions....I guess you can see where this is leading...I don't have to pay shipping, now if he would just come loose with some product, I'd tell you his is the BEST...lol! Oops, I guess he did put some in the CS comp class goody bag.
I've been taught by Smokin' to always try one of each and see what I like, so that's my recommendation.
