I think photorealism has the advantage of maintaining a cinematic feel. You can do a lot of 'realistic' things withs light in a game, that aren't really realistic (you'd never see them in real life), but are the type of thing you'd see in a photo or movie. This allows for a more tightly controlled experience. Of course, this all depends on what the intention behind the game is. If you do want maximum immmersion, visionrealism would be the way to go.
