Samsung SCH-A670

OK so I need everybody's help with this one!! If you've looked at the lg 6100 you already know my situation....anyways. I had this phone and yes it was a great phone except for the part where i lost soo many calls!! it seemed like everytime i was on the phone i would drop a call. well that doesnt happen now because i lost my precious phone. so im getting a new phone and cant decide if i should stick with this same one (670) or go with the LG VX-6100???? so if anyone out there can give me some help and advice on which phone is better and which one i should spend all my money on!!! 😛 your help is greatly appreciated...thanks!!!
