D3200 and prime lenses and focusing

I recently purchased a D3200 with its 18-55mm kit lens. My main reason was to see whether the 24Mp sensor would perform better (resolution) than the D7000 16Mp at low ISO using prime lenses. (I already have a D7000 with 18-105,70-300VR, 35 1.8G,50 1.8G, 85 1.8G)
