One strength of Sidestep is that it goes across different sites to compare fares. For U.S. domestic travel on routes where Southwest competes, it's helpful that it compares fares from Southwest, which aren't available on most airfare search engines, with those of other airlines. I think Sidestep used to go only to airline Web sites, saying prominently that this booking would give bonus frequent flyer points; now they also use agencies and consolidator sites. Sometimes they compare fares inclusive of taxes and fees with those without taxes included. As Russell reports, sometimes there are technical problems when you're taken to another site to complete your booking. If that happens, you might take note of the site you're being taken to and try to go directly to that site to book the trip, or see if you can find that fare by other means.
