I have both, a 1949 vintage Model 94 in 30/30, and a 1980's vintage "Ranger" (their cheapest version). The 1949 vintage rifle shoots better, has a higher rear sight elevator for longer ranges, a hooded front sight, better quality wood (real walnut), seems like a smoother action, trigger is nicer, too. It is a "Top Eject", where the emptys land on the bill of your hat, while the later rifles had an "Angle Eject", kicked them out to the side so you could mount a scope easier. I have seen many Pre-64, top eject rifles ruined in my opinion by people drilling holes in the side of the reciever for a side mounted scope.
Here's some pics of mine:

1980's vintage "Ranger" with SKS sling and butt stock ammo carrier, my truck, canoeing, survival and utility rifle:
The Ranger I got for $250, it shoots good out to 100 yards, haven't tried it any further.
Both rifles, side by side:
I did find a good cast lead hand load that works good in the older rifle, a 165 grain lead flat point bullet with 9.5 grains Unique pistol powder, good for around 1200 FPS. Accurate, no recoil, fun to shoot, quiet enough you can shoot them without hearing protection. I have to raise the rear sight to the highest level, this gives me point of impact = point of aim at 50 yards, and groups around 1.5 inches. I can't use these loads in the Ranger as I can't raise the rear sight high enough to hit point of aim, they hit about 6" low in that rifle. These loads are good for small game, general plinking fun, and introducing new shooters to center fire rifles.
