OSB is much more nuanced than particle board, often in a bad way. Many manufactures orient the chips along a single axis, meaning it shares the anisotropic properties of solid wood where the X axis has a different strength and expansion rate than the Y axis. And looking at the 3rd dimension, the Z axis is actually quite weak. If you glue something to the face of an OSB board, you can break the joint fairly easily because the individual chips pull out.
