I've made a lot of different varieties of jerky out of venison, beef, turkey, and ground meats in the smoker and dehydrators and the dehydrator gave the most consistent results, especially for the ground stuff.
The first dehydrator I used was a Nesco and it did okay but it was more like cooking than drying it out. I bought an Excalibur which cost quite a bit more but did a great job because there's a temperature control and the fan and element is at the rear so you can dry the jerky at a low temp. I also used it for making dried apples, banana chips, apricots for my kids and it worked great for that too.
I used the guns quite a bit but the best ground jerky I made was jalapeno and for that I'd mix the seasonings and diced jalapenos and then pack it into 1 or 2 lb game bags, like Jimmy Deans comes in. Then after it was frozen I'd slice it on an electric slicer about 1/8 - 3/16 thick and put it on the racks. Completely different texture than from a gun, more like a chewy salami. If you like jerky, making your own is a helluva lot cheaper than buying it and you can tweak the recipes to your own taste.
I use the smoker for things like sausage, venison salami, smoked salmon and jerky but it's a longer process and you need to add cure to prevent botulism.
