Biggest leap from one system to its successor in the 3D era in your opinion

[curl-6]

The generational jump from the primarily 2D 4th gen consoles to the 5th seems to be widely considered the biggest generational leap, but what of those that followed? 

In the 3D era (5th gen onwards) what do you think was the biggest leap from one system to its successor?
