You're supposed to floss before you brush. Cus just rinsing won't always take away whatever you just flossed, but brushing will. Plus you can brush under what the floss took away, rather than brushing on top of something.
I brush then floss.. although I dont floss everyday.. maybe 2-3 times a week.. I always forget until I jump in bed, then I'm too lazy to get back up and do it..
i floss after, just to get anything else out that the brush missed. have to floss everyday! its like brushing ur tongue, once uve been doing it for a while, ur mouth doesnt feel clean unless uve done it
