Definitely the smoker.
I had the same dilemma last year with a bunch of deer jerky. I ended up doing 1/3 in the smoker, 1/3 in the dehydrator, and 1/3 in the oven (mainly because I couldn't get it all in the smoker in a single batch and because I wanted to see what turned out better). The smoked jerky turned out way better than the others. I used store bought cure as my base and then added different flavors (teriyaki, mesquite, etc.) to them, so I can't help with a recipe.
