The practical advantages of it have a lot more to do with timing, prep dynamics, and consistency than they do with final quality.
There are some things that it makes possible or easy that are otherwise nearly inaccessible to home cooks and that is cool if you want to play around with it. Or if I'm cooking 6 steaks for guests or whatever but that's not a problem I've been having recently. But otherwise I don't find too much value in it personally.
