Perhaps it is best to accept that SpaceX is a unicorn.

What exactly is ground breaking about SLS and not quite getting back to the moon with it?

I don't know or care about some classification of SpaceX, but about what they do. My description is accurate, I think.

I don't understand the second part: NASA doesn't do groundbreaking work, because you found one project, in progress, that hasn't broken new ground yet?
