It all depends on who's going, where/when you're going, what you're going to be doing once you get there and how you're going to get it all there.
I've only used checklists early on when I first got into backpacking...
They seemed to work OK, because my back was hauling everything.
When I take my kids camping... I sit down and mentally picture what we're going to be doing, what time of year it is, what we're going to eat... then decide what I'm going to take.
Once my teardrop is done about the only thing I'll need to pack, is food, clothing and any "toys" I want to bring along.
I don't really see much of a need for a checklist with a teardrop because it will pretty much just stay packed and ready to go at a moments notice.
Experience can be a good teacher...
I forgot to check to see if I had spare mantles for the lattern on more than one occasion and we went to bed pretty early a couple of times after the lattern got knocked over.
Oh Yaa... I've forgot river shoes once or twice too, so if you forget something you really need enough times, you'll eventually remember to bring it next time.
