Super credits out of points of interest, all three sample colours, medals for the warbond back catalogue, and requisition for stratagems. None of it is difficult once you can survive the difficulty it drops on, which is exactly why the difficulty page is upstream of this one.
Difficulty six if you cannot clear it, because super samples and the ship modules behind them are locked until you can. Then the samples. Then warbonds, which are the slowest catch-up in the game. Levels last, because they unlock less than people expect.
