Summary: Versace Pour Homme is not the same as Allure Homme Sport to me. I can see a very slight resemblance at times, but AHS really is a very different scent and much more calming and smooth to me,... while Versace Pour Homme is sharper and has a great distinct floral scent hovering in the background behind a more aquatic vibe. AHS seems to be blended perfectly and smells of higher quality to me. But, that doesn't mean I prefer it over the Versace. They are both great scents.
Summary: I own both this and Chanel Allure Homme Sport. Both are great fragrances, but I still scratch my head at all the comparisons between the two, and how many people say they are IDENTICAL. To someone who doesn't wear fragrances, and particularly doesn't have an interest in them much or isn't as sensitive to smell as others, maybe they'd think they were similar, but that's all I can see. I see a huge difference in both.
