The OEM checklist may be well-designed, or it may be absolute trash that is literally unusable. Like, I remember King Air landing checklists that went all the way up through "Brakes.... APPLY" and things like that. How are you ever supposed to complete it? It wasn't made with any forethought as to when each item would be performed with respect to when the checklist could be completed, when is an OK time to be heads down looking at a piece of paper, etc. Someone just puked out a list of steps in operating the airplane and called it a "checklist" and that was that.
