Simp_le does the same thing. I use simp_le with Haproxy on one server and nginx sni on another. Works very well.

No, simp_le does not do the exact same thing. simp_le will also generate certs and get them signed, but certbot will install them in apache for you. certbot is for people who don't know or care how to install a TLS cert and just want the thing to go green

Certbot supports both use cases; "certonly" stops after getting the cert; "run" installs it if there's a plugin available for your webserver.
