The Shuttle consisted of the shuttle (orbiter) itself, the external tank (not reusable), and the two boosters which could be reused after ocean recovery. The orbiter itself was slow and expensive to reuse since (among other things) all the heat shield tiles were inspected and 30-100 replaced between each launch. I don't know how much work was done to the engines between launches, but SpaceX's parts and cost reduction on the Raptor engine have to give it an advantage there.

StarShip consists of the Super Heavy booster that we saw "caught" today, and the StarShip (orbiter) itself. Having the booster return to launch site vs requiring ocean recovery should potentially increase cadence and reduce cost of reuse. StarShip is also meant to be reusable, although it remains to be seen how that will pan out. On the previous flight there was burn through from inadequate heat shielding - maybe we'll see an improvement with today's vehicle. I'd expect SpaceX to iteratively arrive at a quicker and more cost effective orbiter reuse procedure than NASA had with the shuttle, but how quick remains to be seen. Of course they are planning many of these to go on one-way trips to Mars rather than being reused.

Worth noting that Starship's heat shield is very similar to the one of the Shuttle. They actually got the manufacturing method from NASA.

That's why I remain very skeptical about the easy refurbishing of Starship. Initially, way back around 2016, the plan was to vent liquids to create a cushion around the ship. That sounded more easily reusable.

Yeah. I think they originally planned to use ceramic tiles only for certain spots and still transpiration cooling for the rest. Then they fully switched to ceramic tiles. In an interview with Everyday Astronaut on YouTube, if I recall correctly, Elon Musk said they first believed the ceramic tiles to be lighter.
