I prefer to use semolina, since that's the same flour the pasta is made of. I find corn starch can add an "off" flavor.

corn starch is widely used because it has no taste raw; a flour based roux needs to be "browned" in oil to eliminate the floury taste (i've tasted the grain of wheat from a plant in a field: tastes floury)
