The important thing here is to differentiate between "quick" actions and "correct" actions.
Years ago, aircraft evacuation checklists (both Boeing and Airbus) were considered memory or recall items. After a few less-than-perfect evacuations, wiser heads suggested that it was more important to accomplish the required actions
correctly rather than quickly. Accordingly both manufacturers re-wrote their manuals and made these reference, or read-and-do items.
Very few situations in an aircraft require urgent actions, but all situations require correct actions for a successful outcome.
