• Best-in-class desktop application support, including legacy Windows technologies.
• Object repository keeps recorded tests maintainable at scale.
• Full C# escape hatch for anything the recorder cannot express.

• Everything included: runner, assertions, page objects, reporting, parallelism.
• Very readable chained syntax that non-specialists pick up quickly.
• Tight BrowserStack integration if you already use that cloud.

• Windows-only authoring environment.
• Expensive per seat relative to open-source web tooling.
• Web automation is competent but not competitive with Playwright.

• Community is a fraction of Playwright's or Cypress's; fewer answers exist for edge cases.
• WebDriver-based, so it carries the usual latency and waiting caveats.
• Corporate stewardship by a device-cloud vendor is worth weighing if you plan to use a competitor.
