Since you can reload both rifles, allbeit one slower than the other, I don't think the pump-single shot thing is an issue. The '06 has more reach and power. If you can shoot it accurately, go with the '06. If you shoot straight the first time, a fast follow-up isn't an issue. I hunted deer with a single shot '06 for 30 yr's and never lost one due to a lack of follow-up speed.
