I've been using pre-64 M 70's for a long time, and have quite a nice collection in quite a few calibers. My favorite going hunting rifle was my pre-64 M 70 in 300 H&H. Damn, it is one accurate rifle. Stopped using it because of the rarity and it's value I personally place on it, and it's still in excellent shape despite the use I gave it.
My main hunting rifle, know, is a 1951, M70 in 30-06. Back-up rifle is a pre-64 M70 Featherweight in 308. Both are super accurate. The reason I enjoy using them is: 1. the control round feeding 2. three- position safety 3. the stock design and the wide butt is a pure pleasure to shoot. Just like riding a fine horse. 4. I appreciate and admire the simplicity of design and the hands on quality of manufacture. 5. They're a damn fine looking rifle as well. Much like a fine looking woman that knows how to please you. There's more reasons, but this enough, don't want to over kill. .
If I were to buy a new one, it would be the new M70 Classic. The reason I would consider a new one would be for a stainless version with a plastic stock. This way I could take it after sheep and not worry over scratching up a pre-64 stock the stainless would be easier to hunt with in severe wet climates.
I'm not saying anything against the Remington, because they are also a fine rifle. But in buying a new rifle, it would be the M70 classic.
