Samsung SGH-D807 / D806

hey everyone, i wanted to ask what everyone thought of this phone who currently owns one. i have been wanted a slider that is really good for the past few months. i know how this phone feels and looks because my roommate has the t809 for tmobile. i just signed up with cingular this weekend and picked up the razr v3. so far i am happy with the v3 the only things i don't like about the v3 are the low earpiece volume and very week vibrate. also not a phane of the moto UI. i wanted to see if this sammy would campare to the moto in terms of battery life and reception is it better or worse? all replies would be helpful.
