There is no objective "best" console. The Xbox 360 (2005–2016) was a landmark system with massive impact, but "best" depends entirely on individual priorities.
The 360 is arguably the best "online ecosystem & controller" console of the 7th gen. It's the nostalgic favorite for Western shooter/action fans. But PS3 wins on exclusive variety/media, Wii on innovation/sales, PC on performance. "Best" = your favorite games + your preferred playstyle.
