I picked written but it really depends on what it is-
For lace- charts
anything with cables- written (not sure why- even though the symbols are pretty much a picture of the cable I still have a hard time without the written directions esp if it's more complicated than a c4b or c4f)
colorwork- charts
Everything else I will usually pick the written instructions. I write each line on an index card and group instructions/rewrite in the way it makes sense to me.
I think the reason I prefer written most of the time is that it's easier to keep my place if I have to set it down- my youngest adores moving my magnets around on charts, or the dog paws the thing & rakes the magnets off, etc.
So chartwork is only when the whole house is asleep.
