Fact check:
Starship was in development for much less time than SLS, it costs order of magnitudes less and it had several successful 10 km flights.
Your comment is absolutely misleading if not outright false because starship as we know it with the steel construction is from end of 2018, so a little more than 2 years ago. The current testing pace is two launches in less than 30 days.
SLS had a failed static fire in January and it took them 3 months just to do another static fire.
Starship performs multiple static fires per day and it’s the only vehicle in history that managed to fly with full flow engines.
