I'd be very interesting in hearing more about this.

I tried using both the Consul and etcd Raft implementations as libraries. I found the Consul library much easier to interface with. But it was my impression that the etcd library was much more tested in the real-world, with big projects like Kubernetes and with the library being embedded into projects like CockroachDB. I also wasn't sure if the details that the Consul implementation was hiding were actually important.
