The shuttle had wings, Falcon 9 / Dragon does not. That's also why it had expensive/brittle tiles rather than ablative shielding, was strapped on sideways, had solid rocket boosters to handle the added weight, and didn't have an eject capability. Also all of its stuff splashed at parachute speed into the sea. The shuttle wasn't so much reusable as rebuild-able. By contrast this SpaceX concept looks like it could pretty much be stacked back up, fuelled and re-launched.
