None of these offer much advantage over the other. With the exception of gun nut's it kinda sounds like either you like what you have or you like a particular model rifle. For myself, i'm not real sure other than it wouldn't be a 30-06 (every body shoot's one) and it wouldn't be a magnum. I'm not a 270 fan so it would be a 25, 6.5 or 7mm. Take your pick.
