I concede your point.
I suppose the nice thing here is that we both now have two ways of doing the same thing.
I've explained why I prefer running the underlying tooling; hopefully it will be useful as one of those snippets of internet knowledge.
Independent of debugging, I would contend that this set up is better than running babel-node with something like nodemon, again, because of much better reload times.
Again, thanks for babel-node-debug, I've used it before, and I won't be too surprised if I find myself reaching for it again in the future.
