Both are great warm weather frags that get compliments from girls. Chrome projects and last longer imo and is more fresh has a metallic vibe to it. Allure homme sport is more citrus. Both are great tho so goto your local macys or dept store and give them a test to see which you like better
I think Chrome Azzaro is probably the best choice for you. I think Chanel Allure Sport is the better fragracne, however being a teenager Chrome is a better value. Now if money is no object to you, then I'd totally recommend going with Chanel Allure Sport.
