Its all in the name of marketing, which company wants to spend the most at getting your attention and dollar, in my opinion, If your fav man crush fisherman is say jason mitchell and he's pushing zzz brand fishing line feeds you all the hype on his show about the line, you run out and buy it, just because jason mitchell says its good line. Then you have QQQ brand line just gets their foot in the door convincing some small outdoor store to put it on its shelf for half the price of zzz line, and everybody thinks its junk because they don't advertise it.
But every brand has its pros and cons.
