Ranked by median difficulty, easiest first. The bar is a range, not a label — a channel typically spans a wide stretch of the scale, so one level would be false for its own hardest videos.

The vocabulary range is each channel’s own spread, not a single verdict: in three of every four of its videos the vocabulary starts at the lower level or above and stays at the upper one or below. Its top end tracks how far the rare words reach, so a channel devoted to one subject sits high on it without being hard to follow — the median score is the column that answers that.
