Quick impressions: A week of using Codex more than Claude

The author compared using Codex versus Claude for Ruby/Rails development over a week, noting that Codex produces simpler, less-commented code and makes changes faster, but Claude handles more complex cases and understands context better. Codex's output is more technical and less conversational, though it struggled with branch management and integrations, while Claude proved more adaptable to the user's preferred workflows.
