I use both every day. The core perl5 packages I rely on are updated regularly. The perl5 runtime is released on a reliable schedule. Everything works.

I use raku mostly for fun. It has come a long way. It has further to go, but I don't mind. There is a surprising amount of vital packages already available for getting things done.

I don't think anyone believes perl5 will be as popular as it was years ago, or that raku will be a top-five language, but who cares? As long as the core community persists, its enough.
