Garmin and Tom tom seem to be very simalar, it almost like a toyota and lexus, Lexus = Expensive toyota. So Being that tom tom are cheaper and a garmin has no real advantage of a tom tom i would have to say tom tom. The Other companies are just utterly annoying, Tom tom says whats gotta be said and thats it. no ads not BS just plug it in and go.
