VG is putting tourists into sub-LEO. SpaceX is building rockets that can reach any orbit, carry many tons of payload and even send manned missions to the Moon or Mars.
When Musk started SpaceX he decided to use tried and true designs and instead focus on refining those designs for performance, safety and cost. He did so by moving the entire manufacturing chain in-house. Many would argue that he has achieved his goal.
Rockets (which usually have to be multi-stage) are more cost effective and more capable than the Shuttles. The Shuttles are too fuel hungry and too inflexible (in the configuration they settled on) to fly to the Moon or Mars (or even move beyond LEO). They are not "space planes", capable of zooming around space at will, they are Earth gliders with rockets attached.
I haven't read his rationale for the self-landing rocket stages, but I would guess it's about recovery costs. It's not cheap to track down and fish rockets stages out of the ocean. They also have to be completely rebuilt after their plunge into salt water. Heat damage is likely an issue as well. If keeping that amount of reserve fuel would not limit the rocket's main mission, it would undoubtedly save a lot of money in recovery and restoration costs.
It's progress because the Shuttle missions were a step in the wrong direction if the ultimate goal is to make space accessible. Well designed rockets can be more capable, just as safe (if not more so) and can operate at a fraction of the Shuttle program's cost.
