My recommendation would be either.
RAZR:
yay:
Moto quality radios
Separate HDMI port
ACCESSORIES!!!!
SD Card
Webtop
boo:
When ICS comes, it's questionable about the soft buttons. You could have SEVEN buttons at the lower portion of the phone
Non removable battery
VZW SGN:
yay:
ICS, duh, and that's a huge point
NFC unofficial support (free ten bucks from the google!)
Better display (720) on screen
MPT (can access internal media at the same time through the phone and while on usb)
Removable battery!
boo:
Lack of quality accessories like dock
No separate HDMI port, need a separate aftermarket powered adapter
No sd card (micro) slot

There's probably a lot more, that's my 2 mins of thinking about it, and I've thought about returning and trying a RAZR
Again, not only try the phones in-store, but also think about how you will use it for as long as you own it. Do you want to connect the charger when it's on a car/windshield dock, or have it ready so you just dock and go? There's not an all-in-one dock for the SGN... yet.
Just trying to bring up some points, you probably have researched already. I love my SGN, and there's probably no chance that I'll swap to a RAZR.
