Comparing one- and two- stage rockets is a bit of a handicap, since no one (yet) is talking about landing a single-stage-to-orbit rocket.

The best numbers I can find say that the Falcon 9 stage separation is at around 80km and 2km/sec (2.8 MJ/kg of total energy), and the Falcon 9 has so far failed to land under power.

Yes, there are lots of subtleties about staging and so forth, but lots of people are talking about that elsewhere. I just thought I'd put some number to the simplest possible case so people can see the magnitudes we're talking about.
