How does ergo compare?

How does ergo compare to this similar library in terms of performance and developer experience?

I'm not super familiar with this framework.

The only pro I see in this framework is using lock-free MPSC instead of channels for the actor's communications. It makes communicating a way more performant. I already have a task in my roadmap to implement communication the same way in the future.

The cons - it doesn't provide a native way for interop with Erlang/Elixir cluster, it doesn't have a Proxy feature. I also don't see anything like Monitor/Link features. It doesn't check the incarnation of the process. I haven't found a way how to make sync requests.

I should also mention that they use GRPC, which is a pro for some cases but could be a con for others.

Anyway, it's a good framework. I suppose I miss something and would appreciate it if anyone else could make a way more expressive comparison.
