I think he has more talent, is more versatile and is smarter than Jackson. We haven't seen what Darnold brings because he was drafted by the worst, least talented team in the NFL - from ownership to waterboy. Jackson was drafted into a great situation from top, down. Surrounded by talent and has a great defense behind him. But he's not good enough to lead the team further than making the playoffs. He's a runner and primarily passes to only easy targets over the middle. Darnold has a lot more to his game and his highter intellect will make him the better QB.
