The One was a miss from the beginning , trying to be more than a gaming console and falling short on all fronts. The name didn’t help either.
Then they picked an even worse name for the Series X and and Series S. while implementing a necessity for parity. confusing the market and holding back devs.
The 360 was effectively a flash in the pan IMHO, helped by a significant misstep on Sony’s part with the PS3 design, and Nintendo moving to create their own market with the Wii that effectively made it a companion console rather than a competing one.
