When note taking, a concept map would be preferably better due to its ability to differentiate the importance of the information.  In my opinion, it helps organize better as well so when you look back at them, you will know where everything is (not only you but whomever has access to it).  Concept maps also look more pleasing to the eye rather than seeing a bunch of words scattered all over a paper. Concept maps also come in handy for quick reviews before exams, homework, and more. Also they can be fun and maybe easier to remember because of the fact that it isnt a bunch of words all over the place. It can be seen more as as graphics/drawings to remember.
