For a black interior, I would pick the LC's dark grey. I love the super white, but I think it might look a bit funny with black interior. I have had white with grey (80 series) and white with tan (100 series) and out of them, I loved the white with tan combo best. Black interior just seems to need something darker on the outside for me.
One of my favorite things about my 4Runner Trail is that the paint is Super White and everything else--exterior trim and interior--is black or dark gray. I think the contrast looks awesome.
