NGINX vs Azure Application Gateway

Four of fourteen models named NGINX first on the direct prompt; one named Azure Application Gateway. NGINX was named by fourteen of the fourteen models and Azure Application Gateway by eight and NGINX carries 53 labels and Azure Application Gateway 10, so the shares are not directly comparable.
