I'll make a recommendation here. For many rendering projects I keep producing and improving styles since each presents different settings I need, not just quality but backgrounds, artistic edges, camera effects, environmental reflections, number of bounces, light intensity, grass, displacement mapping, etc.
All of those I keep track of saving them in a favorites file, same for backgrounds. Here you have a couple of samples, one made with an artistic style, notice the thin edges and the other one a bit more real, including some camera effects.
