Just because it dusts, doesn't mean it should be thrown away, it is one of the best polishs money can buy. You just have to mix it with something that will minimize the dust; RMG, Optimum, any oil based polish added, even in minimal quantities, will stop virtually all of the dusting. If your budget allows, get both OPT and Menz, they both have their pluses and drawbacks. I use both the Menz and the Optimum, and I would never dream of tossing one or the other out b/c of some side effects they may have.
And a companys public appearance can show what they are, but the ol saying "don't judge a book by it's cover" is all over this. Optimum is a great product. Their website may not look good, but sometimes, I'd rather a company put more time into the product, than into it's outward appearnce. That goes for a lot of the products AG sells; Poorboy's, DP, Duragloss, etc. all have the "no frills" packaging, but that doesn't mean the products are junk.
However, like a lot of threads on here, I doubt that will change any minds on the issue.
