They're both pretty heavy for whitetails, but they'll sure get the job done. I think a hard-cast lead slug out of either would be a good choice, and handloading opens a lot of opportunities. The .444 can use .44 pistol bullets for plinking and varmints after deer season. If .35 Remington, .356 and .375 Winchester are legal in OH, they're all great deer calibers, too.
