I use the paper every day - sometimes an internet article to share or keep school lessons weekly letters to my children household lists etc. On and on ever on. This is the only paper I use except for an occasional photo on the professional glossy paper.
It's paper as long as you get brite white they are all the same for business use. Watch out for recycled paper. It might be a cost saver or good for the environment but it is usually very dull or yellow and will never impress a client.
