I have not had great experience with the Motorola phones. I have found their emphasis is on style and less on functionality. And they usually carry a cost premium due to their popularity. I have had very good experience with several LG phones. They tend to emphasize good functional design but they don’t look as cool. They also tend to have more features for less money, maybe because they have to compete with the good-looking razr’s.
That’s only very general information. I would not be able to comment on specific models. Hope that helps!
I can’t recommend a specific forum, but I know they have forums on the web that discuss the current models. I use the Verizon XV6800 and love it. Try Google, or you can try this new search engine that’s in beta testing, www.searchme.com. It has a really cool interface.
