I don't call a >15% performance gain "boring".
And it's got "Coffee" in it.
Based on the reviewer's observations about total cost, the i5-7600 would have been a better comparison, making the choice more obvious.
Additionally, increasing frequency exponentially increases power demand.
It was nice to see my 2500K on the gaming benchmark; I wonder how it would have placed at it's current speed (4.2GHz)--makes holding off until Cannon Lake easier...
