I've owned both, and of all the Chanels I've owned over the years these 2 are the weakest. Both are great smelling, but no staying power. You are better off with Egoiste and Pour Monsieur Concentree. Especially Egoiste, it's very potent and lasts hours on end. Keep in mind it smells nothing like Platinum Egoiste so if you ever give it a go, better try it first.
Allure Sport is worth mentioning. I had a sample of it and it lasted quite a while on me also, which is not easy to do.
