I have a Motorola Q, a Motorola KZAZR, and a Nokia 6315. I'm partial to the Nokia for several reasons:
The memory card can be inserted from outside. No need to remove the battery. You can pop it out and stick it in the pc. The Nokia support a 2G card.
The Nokia camera has heads up display for both FLIX, and PIX, unlike the Kazer which only has it for PIX.
Both the Nokia, and the Kazer (spelled wrong), are programmable from getbackupnow.com (VZW). The Q is not, and it's a pain in the ass to backup, and update.
The Razr does allow me to lock the music player, like my IPOD, or most MP3 players, but the Kazer does not play AAC like the IPOD or the Nokia.
I also like the ringtones more on the Nokia, although I have the Qlacomm tools, and several LINUX boxes to make my own.
Ironically, VZW, has move away from the Nokia. I had some problems with 3 phones in a row. Bad receiver, bad mike, bad OS load. I still like my Nokia best, though.
