The viscious hooksets come into play when using wide gap single hooks and especially when using jigs that ride with the point up. It takes a good sharp stroke on the rod to sink a big or thick hook into the upper mouth/jawbone of a bass. The other issue is with small fish or one that is swimming towards you. A less agressive hookset will pull or glide the fish through the water and you may not bury the barb. Sometimes there's not a lot of resisitance to swing against on the fish's end of the line. With super sticky fine wire hooks, dropshot hooks, treble hooks, in lips and other soft tissue, - it doesn't matter as much.
