I, personally, like to mix the way I write out dialogue. I'll end a paragraph with dialogue. Start a new paragraph with dialogue and then describe what they did as they said it or what they did after speaking. Then I write a response, describing what that character did. And then I'll stop using descriptors and continue with strings of just dialogue where the reader understands that it's between these two characters and have learned a sense of their personality by previous descriptors. I don't like the idea of flooding dialogue with extraneous descriptions since it breaks the flow of natural dialogue and will take away from the reader interpreting the characters on their own. If I'm a good enough writer, I gave them enough information so the reader can subliminally insert information. However, I've seen dialogue in the manner in the second example: Dialogue Description Dialogue Description It's very choppy, yes, but it, like any other formats, can have its uses.
