I would suggest that a 300 Win Mag or 7mm Rem Mag are not good choices if it's your first deer rifle. Recoil on these is quite substantial, which can lead to flinching problems. So, I'd need additional info from you:

Is this your first deer rifle? How much shooting experience do you have? Is it only for whitetail deer, or are you also planning touse it for bear, elk, moose, caribou, etc., etc., etc.? What kind of yardage will your shots typically be?

Any of the rounds you've listed would be more than sufficient to kill deer. It's these other considerations that will lead to giving you good advice.
