 ### Why to use Crawlee rather than Scrapy?
 
-- Crawlee has out-of-the-box support for **headless browser** crawling (Playwright).
-- Crawlee has a **minimalistic & elegant interface** - Set up your scraper with fewer than 10 lines of code.
-- Complete **type hint** coverage.
-- Based on standard **Asyncio**.
+- **Asyncio-based** – Leveraging the standard [Asyncio](https://docs.python.org/3/library/asyncio.html) library, Crawlee delivers better performance and seamless compatibility with other modern asynchronous libraries.
+- **Type hints** – Newer project built with modern Python, and complete type hint coverage for a better developer experience.
+- **Simple integration** – Crawlee crawlers are regular Python scripts, requiring no additional launcher executor. This flexibility allows to integrate a crawler directly into other applications.
+- **State persistence** – Supports state persistence during interruptions, saving time and costs by avoiding the need to restart scraping pipelines from scratch after an issue.
+- **Organized data storages** – Allows saving of multiple types of results in a single scraping run. Offers several storing options (see [datasets](https://crawlee.dev/python/api/class/Dataset) & [key-value stores](https://crawlee.dev/python/api/class/KeyValueStore)).
