I typically use a custom export setting from 3dsmax to OBJ. The Zbrush preset is ok to use as a starting point for making your own custom OBJ export preset, but you will likely need to add more settings. You have to decide if the model will be used for 3d printing, or is it a CG asset for games or VFX? Do you have textures that the OBJ should use? There are options to select for all of these variables. OBJ is still very popular, but people are moving away from OBJ in favor of FBX as a much better and more reliable exchange format for most CG assets.
