Motorola W755

I amm looking at getting a prepaid service from Verizon. The two phones they have available that I'm interested in are the Moto w755 and the LG vx5500. Would anyone have any experience with both these phone as far as reception? I live in the mtns of western NC and would like to purchase the one which has better reception. I was told buy a sales person that the w755 has dual internal antennas. He said the 5500 was new and he didn't know about it. The 5500 at $50 would cost me less than half what the 755 is at $120.Thanks.
