Personally, I work for Verizon Wirelesss, and here is my opinion. I like the keypad better on the Voyager, I like the touchscreen better on the Glide I find it to be more receptive...Cameras are pretty much a wash, screen on inside of Voyager makes using HTML browsking easier (again IMO)...and finally I think the signal strength is stronger with LG's opposed to Samsung's.
Hope this helps a little
