Andrew Luck, Russell Wilson, Colin Kaepernick or RG3?

Who do you think is a better QB? Don't just say, for example: "Luck!" or things like that, tell me why you think that.
Update: I didn't add Cam Newton or other QB because these are the last season's rookies. I know Kaepernick isn't a rookie, but that year was his second in NFL and first as starter.
