There are limitations on the smaller smokettes, one of them is the temp limit of 250. Also, by design they tend to keep the air very humid so the skin doesn't "dry" out enough to crisp up.
Brining is a salt solution and to some they'll think it salty, others not salty enough. Just like making your own rubs, you can reduce the salt in the brine (but you can't get rid of it).
If you're smoking turkeys to the point that you throw away the skin, that's fine for you. I think, what most people are trying to achieve is the Visual Effect you get from a 350 oven -- that golden skin look so when you put it on the table it looks great. Hard to do right in a smoker, because too much turns it dark.
That method I've posted here for years, about brining and then using cheese cloth works around here and get a good lookin' turkey.
Here's how my turkey's come out:
