I think there is some confusion over quality vs. quantity.

You can ship all the code you want, but even if it's lots of mediocre code, it's still mediocre.

Quality is independent of quantity or productivity. You may choose to lower your quality in favor of a higher rate of productivity, but you've still lowered your quality.

So you may be a productive programmer. But that doesn't necessarily make you a good one.

There's also the matter of the quality of code that your'e capable of, versus the quality you actually produce. So you may be a very good programmer forced into producing shitty code (time constraints often do this).

But let me say this: a good programmer who consistently ships great, high quality code regardless of the situation is still a better programmer.
