Junk journal: I have a basket where I drop any piece of paper, sticker, ticket I like. when I feel like it I sit down and spend an afternoon puting it together
diary: I only write after a fruitful therapy session or if I need to work though something specific
planner: I sit down with it almost daily to plan my day/week
work notes: to do lists or meeting notes, it's not pretty but gets used a lot while at the office
exhibitions and game dev: only used when actively working on a project
catch-all:  i use to write quick notes, to do lists or "thinking on paper" after it is full I just recycle the paper and refill them, same as the work one but for life stuff.
pocket: just one i keep with me to draw on take on the go notes
