Who would win this 200 meter Race?

Well due to Usain's age he may have the upper hand but Michael will have the experience. This question could only be answered by there being a race cause a lot depends on if they come to the race to win it or if they are just there, and also the starting blocks have a lot to do with the results. But if I really had to choose it would be Usain due to his proper running form. :)
