dw1256,
Think about the features that are must-have/like-to-have for your Droid.
For me the must-have was the ability to provide a 3G Mobile Hotspot.
Only the Motorola Droid X and Samsung Fascinate currently have that ability.
Of these two, the Droid X has the better camera, more internal memory, DLNA support, and HDMI out.
As has been pointed out, your must have criteria could be completely different and your phone of choice therefore completly different.
BTW - My Droid X is syncing flawlessly with our corporate Exchange 2003 server (via TouchDown) for email, calendar and contacts .
