• Identical inspection results locally and in CI — no arguing with the pipeline.
• JetBrains' Java and Kotlin analysis is exceptionally good.
• Licence auditing included.

• Dramatically faster than ESLint plus Prettier, which matters on pre-commit hooks.
• One binary and one config replaces two toolchains.
• Very good ESLint rule migration tooling.

• Value is highest for teams already using JetBrains IDEs.
• Fewer languages than SonarQube.
• Younger product with a smaller community.

• Rule coverage does not yet match ESLint's plugin ecosystem.
• No support for framework-specific plugin ecosystems at ESLint's depth.
• Young project, so expect churn.

JetBrains-standardised teams, especially in Java and Kotlin.

New JavaScript projects and teams frustrated by lint performance.
