Being able to reproduce the same Config across environments is really where these things shine and help you. I think my favorite is probably just straight up JavaScript config files because Sometimes you can actually write JavaScript in them a lot of places don't want you to do that. But it's kind of nice to be able to like I have a V config file and When I run my V Server I automatically open up first specifically for my hot tips. And rather than having to find the one that I'm working on at the moment It just automatically opens it up and says oh you change this one last open it up.
