Using cloudflare is more reliable than using your own stuff which is still an option that nobody chooses anymore because it’s better to choose cloudflare or something similar.

I’m going to go ahead and assume you don’t work with internet security in any way, have no experience in web development, and have never attempted to provide web application services to more people than you can count on your fingers, but if you had, cloudflare is mana from heaven.

So no, then.
