High-energy physics. Yes, literally every paper that's worth your time is on arxiv first. The only time anyone reads from an actual peer-reviewed journal is when something that was on arxiv eventually gets published (you know, a year later) and might have minor corrections. And I don't know a single person that picks up journals for those crucial papers that were never posted to arxiv. What's the point of "formal peer-review", anyway? If you're in the community you talk to your colleagues about what's on arxiv and you know what's good and what isn't. You don't need a journal to tell you.
