Other than when learning a new type (and then only for the first few sessions), the only time to use a checklist as a DO list is when dealing with abnormal situations where the actions could be complex. The manufacturer does not WANT you to commit such checklists to memory, for obvious reasons.
Certain emergencies where time is critical (such as fire) require you to act from memory, then follow up with a checklist, just to be sure to be sure.
The normal operating checklist is usually set up in some logical 'flow' sequence. But not always, as sometimes various know-better chief pilots get in on the act and add all sorts of stuff. They confuse what a checklist is supposed to cover - i.e. those items which if forgotten could endanger the operation of the AIRCRAFT, with stuff that is pure airmanship and has no place in a checklist, e.g. getting an ATC clearance, releasing the brakes, switching on lights etc.
Most aircraft I have flown (and that's many different types) can be flown in normal operations from the before engine start phase right through to shutdown completely from memory if logic and scan flows are used. The normal operating checklist is the follow-up tool only.
