Nginx puts some of the more nifty features behind a paywall, whereas it comes natively in the others. One example of these is supporting SRV-records, which acts as glue for containerized workloads. At Billetto we use Nomad and Consul in our cluster, and internally we expose services with DNS and are using SRV-records, so doing a "$ dig SRV +short _billetto-production-rails.service.consul" will return the local IPs and ports where those containers are running.
