If this gun is strictly for those ranges, I can't see a reason not to go with the 4-12. The beginning power is damn near the same, but at the end you have an extra bump if you really wanna be precise. I put a Vortex Diamondback 4-12 on my (new) series Mini and like it very much. On the flip side, I went with the P223 3x32 for another carbine for just a "slight" bump in vision, so I can use the same gun for shorter as well as longer distances.
