Falcon nine is the best rocket for accessing Earth orbit and sometimes beyond. Getting a rocket that wasn't designed for it to land the booster is an amazing accomplishment.
But Starship is questionable. It's supposed to be big and cheap. It sure is big. Choosing a direct path to upper stage reusability is risky. The risk is compounded by the fact that starship isn't leaving Earth or orbit without refueling. And the refueling job is massive. If any of: payload, reusability, launch cadence, in orbit refueling, fall short, none of it works except being a ridiculously large rocket for earth orbit missions.
