For korean martial arts, 6th Dans should be in their prime, where everything comes together, and where everything you do seems to work.
That helps to demonstrate my point further. If the average skill level of 6th Dans is much higher (because that's the prime time) then surely a mediocre (average for 6th dans) is better than a "solid" lower dan (where the average skill level is lower).
