Sometimes it comes down to personal tastes as to what some people like and don't like. And I'd venture most people who would be looking to purchase either an Anschutz or a 52 Win are a little older. And the Winchesters are guns they are familiar with from their youth. If you asked European shooters in the same age bracket which of these guns they prefer, the results might be opposite.
Personally, I don't put the 64 action Anschutz rifles in the same category as a Win 52. Looks wise, there's no comparison. And going by my own experiences, there's no comparison accuracy wise either. I have seen one 64 target model Anschutz that shot awesome. Have seen a pile of old Winchester 52's that are more accurate than they had a right to be.
Of the 52's, the D's and E's, if taken care of, are simply amazing with how they shoot. Never owned an E, but know people who do and have been around them. But have owned an old B, a couple of C's and one D. Of them all, the D was a far better shooter than I was. Never owned a target model 64 action Anschutz. But have owned a few of the 54 actions. Those are pretty darn nice! But looks wise, I always liked the Winchesters more. Accuracy wise, like any model of rifle, it just depended on the rifle itself. I can say I do love the looks of the old Anschutz Match 54's in the 1411 style stocks. They kind of remind me of the old Winchesters. Own one of those and love it. But still much prefer the old 52D's. Again, I guess that goes back to the fact the older style guns remind me of guns from my youth.
In all honesty, for me, choosing any gun over another comes down to a person's own personal wants, needs or expectations. You buy what you buy according to what you want or like. Other people's experiences can somewhat help with your decision process, but it comes down to what you like the most. Its the same when asking which model is more accurate. Everyone has their own experiences, so their input is based on that. From asking, you can get a general idea of what a particular model of gun might shoot like, but until you actually own or shoot one of those guns, you just don't know exactly how accurate it really is.
