Where are my pants?
Usually a combination of the two--as a previous poster said, it really depends on the look you're going for. Brushes give lighter, more even coverage (I like the brushes that Clinique makes), while the sponge applicators/q-tip method will put on a denser layer that's good for dark, dramatic looks. I also think it depends upon the type of shadow you're using to begin with--some brands seem to go on better with different applicators than others.
