Deciding what rifle to buy is very much a Ford vs. Chevrolet argument, except without as much real difference between the reliability of the various makers.
Much emphasis has been placed on the controlled round feed of the pre '64 Win Model 70/ Classic Model 70, and to be quite frank, I figure that it all amounts to being a great shovel full of sh!t, mostly for the benefit of selling ad space in magazines.
When was the last time you or anyone you know, had to hold their rifle upside down, and slowly feed a round into the chamber? A CRF rifle will do it, but....so what!
Another of the supposed advantages of a CRF rifle, is that a guy that panics, has a harder time of jamming it up by double stroking the bolt.
Well. Maybe. Maybe said individual should not have put themselves where this is of grave concern. It has not stopped the push feed Remingtons from selling very well.
I own a pre '64 M70 Featherweight. I like it a lot. I can drop a round into the chamber and close the bolt on it just fine. I like the three position safety on the bolt, it works for me, and the lack of a detachable mag does not interfere with my hunting in any way.
Looking it over, with an honest eye, it is not that hard to see why there were so many gunsmiths able to make a living. Production build quality was, in a word, poor. Good for the 1950's, but compared to modern production tolerances, poor. A great deal of labor went into each rifle, hand fitting parts, and polishing, in order to make them, which was the lead reason that the design was changed in '64. By the time the "Classic" was reintroduced, production quality without as much handwork was more the norm, so cashing in on the legend was a great business decision. The build quality went from poor, to worse, after 1964, and the older production sure looked good in that light!
Buy any new built rifle these days, from a Stevens, on up, and you can expect performance, out of the box, that many gunsmiths in the golden days would have been really happy to achieve. Todays machining technology is better, materials are better, and barrels are WAY better, on production guns, than they ever were when the "legend" of the pre '64 M70 was shoveled out to the masses.
From the way thing were written up in the magazines, if you got a factory rifle that shot under an inch at a hundred yards, in the pre' 64 era, it was like you won the lottery. These days, it's almost expected from a production gun, and in some, an inch at 100, is cause to be replaced on warranty, or damn near.
The Win Model 70 CRF action is a damn good shooting iron, after saying all that. It should be. Mr Mauser was a damn fine designer!
Buy the rifle you like. Having a rifle you like, that shoots well enough, is better than having a rifle you don't like, that shoots a marginally smaller group on paper. Getting a lemon production rifle these days, is about as common (or less so) as getting a really good shooting rifle out of the box seems to have been in the "old days".
Remington 710's excluded, of course!

slap: to Remington for quality "control"

Anyways. Just my little rant about the legend of the CRF M70 Winchester. Compared to what is available,, and what is routinely expected of a modern production rifle now, the legend does not hold up to the hype. Not in my eyes, anyway. Buy one because you want one. Buy one because it's the one you like, after comparing them side by side with the others. Don't buy one because of the legend, unless you can deal with having the legend potentially die a hard death.
