The Winchester classics from the 90's were probably the best model 70's Winchester ever built. The quality is there. I own 2 from that era and would not trade them for a pre-64, they are much better built rifles.
The problem with the Classics is that sometime after about 2000 quality became very spotty and the closer you got to 2006 production rifles the worse they got. Winchester finally closed in 2006. When buying one of those rifles it is possible to get a lemon, so you are taking a bit of a chance. Like I said I currently own 2 from that era that are great. I've owned 2 others, 1 was great and is one I wish I hadn't sold. The other turned out to be pretty bad, so I'm 3 out of 4 on those rifles.
I also own 1 of the FN rifles. Overall the quality is much more consistent with the new guns. Accuracy is above average and the triggers are coming from the factory at about 3-3.5 lbs and are very crisp. The older Winchester trigger was the most rugged, bulletproof design ever put on a rifle. I actually like the older style better because of it's reliability and open design which can be inspected and cleaned. But it was often quite heavy from the factory and almost always required a gunsmth who knows his stuff to get a good trigger pull. The new guns have great triggers out of the box, but are using a different, enclosed design. While I trust the old trigger more, until a problem arises with this one I'm happy.
If someone were asking my advice on which new rifle to buy the new Winchester is on the top of my list. The new ones are the best USA made rifles at the current time in my opinion.
