As with anything it depends. I'm definitely a code churn out machine (when I'm motivated at least), but I'm not going to say that's a good thing. I've seen others like me who leave a wake of tech debt, and others who don't. Who knows which one I am? People seem to like me though.

As others point out though, the moment something becomes a metric it ceases to be useful. Check out the book "The Tyranny of Metrics" for a breakdown of it.
