They are very different kinds of failure though... This was not an exploratory "try something new" test. This was an integration test to verify that all the "on paper" work was correct. The whole point of SLS is that its use of technology with extensive "flight heritage" is supposed to avoid having to break new ground. This is like discovering a major issue during the shakedown cruise of a new ship. It's better to find the issue now, and that's why they test, but the point of this test wasn't to learn anything new, it was supposed to just prove that it works as expected. SpaceX is generally very up front about tests that they think have a high likelihood of failure, and the tests that do fail tend to be doing genuinely "new things" (like belly-flopping a booster). I'm not a SpaceX fanboy here (I think Elon in particular is pretty insufferable), but it's not really to fair to compare SpaceX's development testing failures with this integration test failure.
