Uncharted 4 looks better, but I think Horizon is more impressive. The seemless open world is pretty massive, and it looks absolutely gorgeous.
Plus, creatures like the ThunderJaw... just look insanely good. I feel in love with Horizon's world. Uncharted 4 more fascinated me with Naughty Dog's attention to the most minute details.
Edit: The Lost Legacy is an interesting topic. ND said it would be more open than UC4, so let's wait and see what they mean. That PSX gameplay was already very stunning, but then again it is Naughty Dog lol
