The achievement is landing a space-capable booster vertically, after an actual mission above 100km, which can then be reused.
Who said that was the achievement? What is important about that achievement?
The important achievement is dramatically reducing the cost of sending things into space (such that they will stay there). SpaceX's rockets achieve this, Blue Origin's don't even attempt to be in that league. Using your Everest analogy, Blue Origin was the first to climb some lesser peak nobody cared that much about (still, nice job), then SpaceX climbed Everest, and Bezos said "welcome to the tall mountain club."
