I don't know the difference with either but I lose very very few fish on Mustad hooks. I pour a lot of bait for clients and friends and very few request Gammy. Some do but most want Mustad.

On all my worm and plastic stuff I use Gammy and only Gammy. Don't know the difference, I guess it is what you get used to.

With that said I like both hooks, I don't think you can go wrong with either, I just like the Mustad for my jigs and shakies. Merry Christmas.
