"They still have the best performing and most feature-ful CDN available."

I don't think thats true. Do you have an actual reference for this? I've used CLoudFlare heavily, along with Akamai, Fastly, Verizon, Bunny, etc.

I would say CloudFlare is the most approachable CDN with a wide set of easily accessible features. Its free tier is terrific too. I would argue that feature for feature, CDN's like Akamai have a much larger feature set, and are also far more complex to deploy.
