I have made made it both ways...............the old cut and slice into strips & soak in the brine as well as the ground.
I prefer the ground jerky better, It is less time consuming, I think the flavor is better due to the fact you are adding the ingedents directly into the meat. And by using a jerky gun, you get a much more consistant size everytime for the drying process.
The texture is different because the meat is ground, but I prefer it not as tough to chew.
The nice part is you run all your scrap through the grinder, freeze it and you use it for soups, chilis, or jerky as needed. I weigh mine out into 2lb sizes, place on the foam trays that store bought meat comes on and vacuum package, works the cats meow.
