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.
A lot of people give the 30-30 cartridge a bad rap as far a accuracy and ballisticsgoes because they look at the round nose of the bullet and don't think it possably could be that accurate. I am amazed at just how accurate it really is. It is also a very easy gun to handle and shoot well. IMO.I don't know about the Winchester, but in the woods from a tree stand, the Marlin30-30 might as well be a laser beam. Who cares about energy at 200 yards. I can rarely see 100. I have a bolt action .270 for the open country, but I don't use it that much because I love being in the woods.

Again, I can't really say many bad things about the Winchester, I just know that the Marlin has done everything I have asked it to do and more.
