3/8 pitch cuts faster. Not by a landslide, but it does cut faster. More life out of .404 though, much more cutter to file.
Both chains in pic are brand new. 3/8 was chisel and .404 was semi-chisel, the semi-chisel tooth looks shorter than the chisel with the lack of the point so a chisel vs. chisel would have been more of a fair comparison.
