I think that the first sentence on the why Pony page says it all
"There’s plenty to love about Pony, but more than anything else, what we love most is that Pony makes it easy to write fast, safe, efficient, highly concurrent programs."
In Erlang you can write safe highly concurrent programs, but you might struggle with fast and efficient. Of course, how much fast and efficient you need depends on what you are trying to do.
