You really can't go wrong with either. You'll need to play with both phones to see which skin you like better, Sense on the Incredible or the Not-So-But-Still-Is-Blur on the X. I played with the X a lot and I don't like the size. There are some things that bigger != better. Either way they will both support Android 2.2 and it will be a matter of form factor. Both phones are terrific but if I had the option I would go with the Incredible. Don't forget that the Droid 2 is right around the corner. It will basically be the X in a refined version of the first Droid.
