I have owned them all I believe . I settled on a 264 win mag and a 6.5x55. The 6.5x257,6.5x284 6.5-06 6.5 CM and the 6.5x51 all shot perfectly well for whitetail poison. I am considering a 6.5 STW like Layne Simpson shoots, however I can do most every thing with what I have . The 6.5x47 I am sure is awesome but after shooting the 6.5x51 extensively, I know it has limitations. I just sold my rem 700 260 dm mountain rifle for $850 to give me money for a Norwegian Krag 6.5x55 and to scope it. It had a beautiful Bishop stock and a rust blue job to die for. The checking is meticulous. So any way you go you will enjoy great accuracy potential and kill power you can't beat easily. Just do it.

SHOOT STRAIGHT AND OFTEN. Hunt with your kids. Teach them not to shoot anything that they are not going to eat. Have respect for all ANIMALS.
