• Shared vocabulary between product, QA and engineering when the practice is actually followed.
• Scenarios double as living documentation that stays honest because it executes.
• Available in every major language.

• Non-developers can read and often write the tests, which matters in QA-led organisations.
• Extends far beyond browsers: databases, SSH, serial, network equipment.
• Extremely stable and well-supported in regulated and telecom environments.

• Almost always adopted as a syntax rather than a collaboration practice, at which point it is pure overhead on top of your real tests.
• The step-definition layer is a second codebase to maintain and refactor.
• Gherkin obscures technical detail that developers need when a test fails.

• The keyword abstraction fights you once logic gets complex; you end up writing Python behind the keywords anyway.
• Verbose syntax and whitespace-sensitive files that are awkward to review in a diff.
• Feels dated next to modern JavaScript tooling, and hiring is harder.

Teams genuinely practising BDD with three-amigos sessions, not teams who just want prettier test names.

QA-led and regulated organisations where readability by non-programmers is a requirement.
