What is a Next Generation Firewall? Which product is better?

A next-generation firewall (NGFW), on the other hand, monitors traffic coming into the Internet, combining traditional firewall features (such as packet filtering and network address translation) with more advanced security features, such as application identification, intrusion detection and prevention, user authentication, content filtering, and security features. f5 can provide a wide range of network and security solutions, including application delivery control, load balancing, WAF, DDoS protection, and other features that protect applications and networks at different levels. nGFWs typically focus more on firewalls and deep packet inspection. As you can see, F5 offers a much more diverse set of capabilities.
