SpaceX built (and rebuilt) a tower practically overnight. They are building two more. They are building huge construction bays overnight. Their contractors are literally working nights. There is probably no comparison on cost or speed. ML-1 and ML-2 have been percolating along for over a decade. ML-1 is going to see just a few launches (3-4?). ML-2 is just 7 feet taller. Total between the two maybe $3.5 billion range? This is just for the SLS tower. Actual SLS / Orion / sustainment costs at the NASA centers are absolutely mind boggling. Then you compare that to what NASA gets with their contracts with SpaceX and the mind boggles.
