We skipper maintainers don't want to really comment on that, because it is very likely that if you do your own benchmarks you show only the good parts and not the bad parts.

From our benchmarks we can outperform nginx in the pure routing case, while nginx will outperform skipper in the pure sendfile case. HAproxy we did not tested, but I would bet it will be not different from the nginx case. IMO: in general use skipper as microservice router and nginx as streaming router that serves a lot of pictures or videos.

Feature wise we have a lot of things to add as HTTP router that you want to run in front of your microservices, please also see our docs: https://opensource.zalando.com/skipper/ Additionally we build a lot of Kubernetes integrations,for example https://github.com/zalando-incubator/stackset-controller which reduces boilerplate and enables you to do automated blue-green deployments and https://github.com/zalando-incubator/kube-metrics-adapter which enables you to do HPAs with custom metrics, for example hpa based on skipper route request per second.
