I think GOJIRA is easily the better film in terms of acting, cinematography, direction, etc. But entertainment wise, I dunno, it's a toss-up. Both are excellent films in different ways, it's too hard for me to choose which I like more.
And I think that the majority of average filmgoers, after watching both back-to-back, would agree with me.
