If you want a shooter the pre-64's are highly over rated, not bad at all, just over rated. SOME have a little interest to collectors if they are in rare chamberings or configurations. If I had one with some family history I'd never part with it, but I wouldn't pay any more for most standard pre-64's than I would any other 50+ year old used rifle in similar condition. The 1960's and 1970's made rifles are probably the least desireable. Quality was down and they were the 1st of the push feed rifles.
By about 1980-2000 Winchester got their act together and were making very good rifles. Guns from this era are good guns and are often undervalued on the used market. Many don't like the pushfeed versions. I prefer a controlled round feed rifle, but conceed for most people it is a non-issue, and the Winchester PF rifles are among the best.
Winchester brought back CRF actions with the "Classic" line of rifles introduced in 1994-2006. These were a copy of the pre-64's with better quality. I consider these to be the best of the Winchesters. You get the pre-64 design, but with modern quality control and the benefit of CNC machining, better barrels etc. Winchester continued making budget rifles with PF actions after 1994, but the top end Classics were all CRF.
Quality started to slip sometime after about 2000 and some rifles, even the Clasics made 2000-2006 may have some minor issues. I've never seen one that a gunsmith couldn't tweak and make right though.
The new FN made rifles are probably the best made out of the box, and I'd highly recommend them. I still prefer the older Classic only because it uses the traditional model 70 trigger. It does not have the best out of the box pull. But a more rugged, simple design has never been made. Most need a little attention to get a great trigger pull, but it is worth the trouble to me. The FN made gun uses a different trigger. It is GREAT out of the box, but is a more complex design. I just prefer the proven design of the older guns.
