I don't have any experience with the Winchester, but the Marlin has been my woods rifle since about 1982. I have spent many hours in the woods with the Marlin in my hands, and when I hold a Winchester, It just does not seem as substantial as my model 336.
i have fooled around with both, and the above statement is on thing most would agree on, the bolt/action on the 94' appears for lack of a better word flimsy, they are however very good shooting guns, that i don't think anybody would dispute, but the apparent week looking and sounding (when cycleing)action, and the scope deal are the biggest complaints i've heard and seen......
btw not saying this in a bad way, just like the time i let my best friend shoot my belgium made auto-5, and he comes back with " man did you know your barrel is loose, this thing feels like its fallin apart"

he hated itand i love it, so do alot of other folks
