Hardware does not determine the ultimate console winner, games do.
Nintendo beat out the PS/PS1, and literally killed many other more advanced platforms because they had a solid a wide game base that others did not have. PS2 beat everyone at the time because they had the games when Nintendo was pushing rehashes. The Wii had the most unit sales, but had weak games sales (especially if you discount hardware bundled games like Wii Sports or Sports Resort), often being beaten or matched by the other 2 consoles on new launches, and always falling behind after title releases, even though the others had a small fraction of the install base. In the end this last gen the PS3 had the better hardware, but the x360 had the game sales and most active user base because they had the solid game lineup which I think puts them as the winner of that console war.
