Hiya Hookman...welcome to the SMF. If you're following the directions from the store-bought seasoning kits, and you like it, why change?
Now, if you are feeling a little more adventurous than the store's seasonings, maybe do some experimenting with them....add some extra heat with cayenne....or try adding some cajun spices.....maybe sweeten up a batch with some extra brown sugar....or possibly kick in some extra garlic and onion powder.
There really is no right or wrong way as far as seasonings go....it's all up to your tastes. If you are actually smoking it, try using different kinds of woods to smoke with....or try mixing some different woods....like apple/hickory....or mesquite/cherry.....etc...
After you play around a little bit and do some more research, you may decide that you can make the best jerky without any store-bought kits.
You will get arguments about whether or not it is necessary to cure your jerky....I prefer to cure it....just cuz I can......others do just fine without curing.
Hope this helps,
