SpaceX, in the last decade or so, has: * Achieved dominance in the commercial launch market, arguably with an even more substantial technology lead. * Performed the first landing and reuse of an orbital rocket booster. * Developed a heavy-lift version of that rocket that has the largest payload to LEO out of any currently operational launch vehicle. Also with reusable boosters. * Delivered a new human spaceflight system to NASA, the first such system since the Shuttle ~4 decades ago despite decades of promises and plans to the contrary. Starliner, the incumbents' entry for the commercial crew program, has not yet flown and is not expected to until later this year at the earliest. * Developed the first full flow staged combustion cycle engine to leave the ground under its own power. It seems really questionable to bet against them at this point, and minimizing their accomplishments to date is really, really silly. Not sure why you have to involve the rover in your comparison, though—it's also a monumental achievement, but it's barely comparable to the domains SpaceX is working in with their launch vehicles.
