Cubic is a genuinely deep peer — micro-agent pipeline, continuous scanning, self-learning, architecture diagrams. Argus's remaining edges: failure scenario simulation (scenario-against-diff reasoning is a distinct bet), BYOK, a computed review contract that routes depth per PR instead of hand-written policies, and a free tier for private repos (Cubic is free only for public). Both are strong choices; pick based on deployment constraints and whether scenario simulation matters to your workflow.
