I think it's largely a stylistic choice. I tend to prefer my ($foo, $bar) = @_;. I did, at one point, do timing tests on @_ versus shift. For my test data (which consisted of object references and strings), I found that shift was generally faster for one and two parameters, both approaches were roughly the same for three parameters, and @_ was faster for more than three parameters.
