Well, yes, but Delta Clipper was touted as a 100% reusable SSTO (Single Stage to Orbit). IMO, SSTO is a pipe dream, and always will be unless rocket science can come up with a new fuel or an engine design that can supply very high thrust at an ISP up in the high 500s or more. SSTO might be possible, but I doubt such a vehicle would or could deliver a significant payload to orbit.
Delta Clipper never got past the hop stage, hovering for a minute or two before landing again. That aspect was surpassed even before Falcon 9 by the Grasshopper test flights. However, even Falcon 9 does not surpass what Delta Clipper was intended to be, a fully reusable rocket - 100% of the hardware being safely landed for re-use. The second stage of Falcon 9 is de-orbited to burn up on re-entry.
Starship is intended to ultimately achieve what Delta Clipper was supposed to... be a fully reusable rocket with heavy light capability. While Starship is not an SSTO, its two stages, but does it really matter at the end of the day, if you are getting 100% of your hardware back.
