I don't mean to downplay Magnus's achievements but wasn't he really more of a gym/comp climber? It's kind of a different sport. I don't think Magnus was ever as good on rock as Alex
edit: I'm wrong, Midtbo apparently climbed a 5.15b. I think Alex's hardest climb was 5.13d, but he also primarily pushes the limits on trad, so it's still not a straight comparison. For context, the hardest trad climb ever done is 5.14d which is 3 grades away from the hardest sport climb ever confirmed (5.15c)
