I think Wonder Woman and The Winter Soldier are both top-tier modern comic book films. To the point that trying to decide which is better is an exercise in futility.
It's an utterly bizarre debate. They are both among the highest rated, most well received comic book films of the modern era. To suggest that one is clearly better than the other by any objective metric is kind of silly. Any difference in qualitative score is marginal at best between the two and it obviously comes down to nothing but personal preference as to which is "better."
