Mule; depends upon your purpose, wants.
If you're looking for a true short action then the 5 or 6 digit New Haven classics are your huckleberry. They are a true short action length as opposed to the P64 is which were all long action.
If you're looking for one rifle to hunt everything I would go with the P64, there is a reason it achieved legendary status.
If I were outfitting a friend, or starting ovet today I would find a nice shooter grade P64 in 30-06, bed in a good McMillan or similar and as our friend Dober used to say, "go fill an ark".
Bob would agree, although he would probably choose the 270.
The P64s ottom metal is a hindrance. Said no one ever.
