At first glance, the Incredible looks nicer out of the box. Sense UI is gorgeous. But the hardware on the X is better. After customizing, the X gets close to the Sense experience with better overall use.
You're certainly entitled to your opinion, but here's what I've found so far:
Much better camera
Bigger screen makes typing a breeze, and better web browsing.
Better call quality and reception.
GPS reception is a push
The real winner is all of us consumers, who have two excellent phones to chose between.
