Verdict
HAProxy Ingress wins on raw load-balancing capability — hot reloads without dropping connections, native active health checks, and superior TCP mode. NGINX Ingress wins on community size, documentation depth, and familiarity. For high-traffic production clusters where connection dropping during config reload is unacceptable, HAProxy is the better choice. For most clusters where the community ecosystem and documentation matter more than edge-case performance, NGINX is the safe default.
