This topic, just as brewing in general, proves that there's more than one way to do it. I think in general, you want to get it cool as fast as possible, especially with the use of Pilsner malt (DMS!). Ten gallon batches are harder to cool so I am an advocate of recirculating the wort over an immersion chiller running cold water through.
Shaving time off of a brewday is never worth sacrificing or compromising the quality of the finished product, so I am more than happy to pump so star san through my chugger after recirculation.
