It isn’t a matter of one being better than the other, but which one will suit your needs better. If you are moving loose material such as fill, modified stone, or topsoil then a grading box is probably your best bet. You’ll be able to move more material into place faster. However, if you are looking to do cuts in virgin soil, crown existing lanes or roadways, windrow material, or grade contours fast then the grader blade is the machine for you.
