Headless web browsers are definitely faster for most automation tasks, but like you said, JS-heavy sites can be a pain. I’ve found that using Playwright with its built-in tracing helps a ton for debugging.
For hard numbers, we ran tests on our e-commerce site—headless was ~30% faster for basic flows but only ~10% faster on complex checkout pages. Still worth it IMO.
Also, check out BrowserStack if you need visual debugging—they let you switch between headless and headed modes easily.
