Shelby Co is not too bad. At least you do not have to pay city taxes. Own anything downtown and have to pay both :(
I don't know to much about Atoka, or Millinton up in Tipton.
To be honest, there isn't much there, and unfortunately, likely require commuting THROUGH some really bad north Memphis hoods to get where you are going.
That's why I try to get folks to look at the eastern part of the city, so at least you can stay close to the main thoroughfare such at Poplar, Walnut Grove. I40
Come to think of it, Lakeland is pretty nice. You get significant distance from the city, and then have woods, lakes, a fireworks store, 10 minutes from 2 gun ranges. right off I40...so a strait shot to basically anywhere FAST.
And if you need to do some shopping, banking, visiting, etc...no sketch to travel through.
Like I say, depends on where your work/office is going to be.
Peek at Lakeland :)
