Even though SLS really needs to die, that sucks pretty bad. It's almost certain SLS won't fly in 2021 now.
Even though the programs are in dramatically different places, it's also striking how different it is for Starship vs. SLS. Starship finds some issues? Swap a couple of engines. Hopefully fly in a week. SLS finds some issues? Back to the drawing board. Hopefully fly next year.
