IMO, the difference is how long you expect the part to last. All u-joints require grease, and the ones without fittings are already greased. It will last until the grease eventually dries out. No telling how long that will be, could be several years. A greaseable u-joint will potentially last much longer -- IF you remember to give it a shot of grease regularly.
