As jhalcott says, check your prospective hunting area's regulations for minimum barrel length requirements. With that question answered, pick the gun that feels best to you. The extra sight radius will likely be helpful to you, as it is to most people, on a target range at longer distances. In the hunting fields, at practical hunting distances out to 80 yards or a bit more, there will be no practical difference for most people. There will be no practical difference in velocity for hunting: 50-75 fps is insignificant.
