It's all the more impressive when you realize that the Falcon series to designed to (eventually) be reusable. Now, the mass fraction won't be anything like as good as the expendable version, and the turnaround time will be significant, (you'll have to sea-recover each stage, install new seals, and reapply the heat shield; but the STS also has a turnaround time for the same orbiter measured in months, even with their reusable heat shield and dry-land capability) but they've given themselves quite a lot of margin.
