How about neither? If it’s a single-person restroom, I pee in the dark corners, behind the toilet, or under the sink, depending on where it’s least noticeable. Or just in the sink if there’s someone right behind me waiting his turn. It it’s a regular men’s room, but empty, do as above but be alert for the door opening! Or stand by the urinal but spray some distance away (like on the wall a few feet away) and be ready to face the urinal if someone enters. If the men’s room is occupied, then the urinal gets the pee except for a “careless” miss or two to either side.
