I took a bunch of pics comparing the interface on the TomTom ONE and Garmin nuvi 200. You can find them at http://www.brothersontech.com/blog/nathan/garmin-tomtom-interface-comparison
I've been using TomTom software for a couple of years, so I'm just more used to that. The Garmin certainly has some perks, but I really don't like the navigation screen. TomTom animates your motion more smoothly and provides a LOT of onscreen data including an arrow showing the direction of your next turn. The Garmin has a better map browser and much better POI and address lookup.
If you are on the fence, I hope this helps you decide if TomTom is right for you.
