I will assume by hunting you mean whitetail deer. If this is so I would opt for a 270 Winchester. It's available in the guns you have listed and has nearly as many loads available for it as the 30-06. The normal bullet weight is 130 gr. and this will be flatter shooting and have less recoil than the standard 150 gr. load for the 30-06. Being new to hunting it is better to buy a rifle that you can manage and become proficient with it. For years my Grandma used a Winchester model 70 in 270. If Granny can shoot a 270 well then anyone can.
