University: Should I use a notebook or a binder?

I use one large binder for every cl. I can't grab the wrong binder by mistake, I always have my work with me, I can rearrange notes for easy studying, I can hole punch handouts and keep them with the relevant notes. I keep a folder for anything I don't want to put holes in and color coded dividers between each cl. I think I only restock on paper once a semester. the binder I used all through college and into grad school is either a mead or five star and it's got a flexible plastic cover and is a 3inch 3 ring binder.
