Nixa is crazy expensive as far as property and real estate taxes. I'm not a fan of the town either. My foster parents retired there, and it just didn't mesh with me. But, Ozark is very up and coming. I live in Bolivar, moved here from Springfield, so I obviously favor the small town vibe. I grew up on the north side of Springfield, but its not the same city any longer. I've never lived on the south side, but as far as shopping, etc it's where I go.

It all depends on what you want. Springfield is the buckle of the Bible belt, and Niva is the epicenter. Springfield is a bigger city, but still has a smaller feel than many. Check out Bolivar, if you want a rural environment. Republic is growing too.
