I added two comments which I think improve the spelling or wording.

The rest is my subjective commentary on the matter of Crawlee and Scrapy comparison, which you can take as a feedback, but also completely ignore. I wanted to provide an outsider perspective, but at the same time, I think the framework creators should have the freedom to express their opinionated view and their ambition how the project should differentiate.

Just chiming in, not approving nor disapproving.

@honzajavorek, thanks for your feedback.

One more thing I didn't notice previously - I'm sorry! Most of the points start with "Crawlee something..." or "unlike Scrapy, Crawlee..." Given the heading already sets the scene, I think we can be shorter by just listing the benefits:

• Newer project built with modern Python and complete type hint coverage for a better developer experience.
• Its crawlers are regular Python scripts. You don't need a separate command to launch them, and you can integrate them directly into other applications.
• Supports state persistence during interruptions, saving time and costs by avoiding the need to restart scraping pipelines from scratch after an issue.
• Allows saving of multiple types of results in a single scraping run. Offers several storing options (see datasets and key-value stores).

Something along these lines. Feel free to drop my suggestion or get just loosely inspired by it.
