Nexus One for the sheer fact it runs stock Android and gets updates instantly. It may not have the best specs but damnitt, it runs the latest and greatest. I don't even have one, I run a Droid X but I wish the Nexus came to Verizon.
Droid X...wife has the DInc and the Sense is super smooth, but my DX with Launcher Pro is just as smooth and is a better all around phone with better specs top to bottom
After using a DInc, OG Droid, Droid Eris, and DX, I have to say the DX is better. However for the like three minutes I played with a Fascinate, and the Evo, I was quite impressed with both.
