Mauser 98 of course, but they are in the US about $2,000 more expensive ($11k) than the Dakota 76 African ($9k).
If you are going to spend this kind of money, you might as well go Mauser. In my opinion (others may differ) the Dakota is significantly overpriced, considering it is but a glorified Winchester 70. Not a bad rifle mind you, but where are the $7,000 value differential compared to a $2,000 Win 70?
Having handled both, I can vouch that the Mauser is definitely heavier built than the Dakota. Whether it is necessary for rifle robustness is debatable, but
I can assure you that a Dakota 76 African weighing in at 7 1/2 lbs in any of the DG calibers is significantly too light. The Mauser 98 weighing in at 10+ lbs makes entire sense.
All this being said,
if it is to be a hunting rifle (as opposed to a safe queen) I would personally buy a CZ 550 .416 Rigby for $1,500; re-bore or re-barrel it to .450 for another $1,000; and give it a B&C Kevlar stock and a AHR upgrade #2 for another $2,000. That would give me a Mauser 98 functional equivalent for $4,500 and I would use the $7,000 balance to get a second buffalo on my next safari
If it is to be a gun library adoration piece, then beauty is in the eyes of the beholder
