Splashback is too often ignored by urinal manufacturers. The angles of surfaces should direct all streams and all splashes toward the drain. When you have a perfectly flat back, the user has to stand further away, which enables direct drip onto the floor or aim-related scattering.
The "piss-on-wall" urinal with recessed floor drain is the... golden standard.
Really, the design constraints for female-use urinals are far more challenging. I have no hope that existing manufacturers can get close to correct there as long as every men's room I see outside of a sports stadium has "bucket" style urinals, mounted at the wrong height, with no thought to splashback or occupancy etiquette.
