I own all of them and trying to compare an SKS with an M1 Rifle to me is simply apples and oranges. Don't get me wrong, I like the SKS better than the G/K43 and SVT40 but it's still apples and oranges because those rifles were all chambered in full size, high power calibers. In some ways, I find the SKS superior to the AK47 and AKM. I have a few of those too including a HungarianAK47 and Bulgarian AK74 post sample machine guns. I admit a bit of bias for the M1 and M14
designs, having collected and worked on them extensively over the years and the old Garand still wins hands down every time in my humble opinion! It's simple, comfortable to shoot, robust and reliable. How's that for a sales pitch?
