If I get an option to choose from composition notebook and spiral notebook, I would go for spiral notebook. As composition notebooks can make better journals. Unlike composition books, spiral books refillable. A lot of time it happens, especially with students, many times it happens that you keep maintaining your notes for a particular subject and your books run out of pages and then you have to buy a new book and continue with your notes but during exams the 1st book you had kept in the drawer, disappears. It creates a complete panic situation and you waste a lot of your time in searching for that which you could have used in studying.

As a student we too passed from the same scenario, but one day we our professor recommended us to use spiral notebooks, we went to the nearest stationery and got ourselves camlin spiral notebook available in A5 and A4 size. The book cover had trendy designs with pp cover shield for daily use.
Its Smoother and Brighter Pages were designed to make our writing experience better.

Also the problem of maintaining multiple books for a sample subject was easily tackled. So, if you are someone who loves to be well organized, I would suggest spiral notebooks
