I've used both Garmin and TomTom fairly extensively, and I prefer Garmin. Considering you can find Garmin for only around $60 (search froogle.com), I think it's a steal. Here's a pros/cons list (all my opinion, of course).

- Garmin's maps seem to be a little better
- Garmin's routing is better
- Easier to enter addresses in Garmin
- Garmin has free traffic (though usually too delayed to be useful), weather, gas prices (very cool)
- Garmin can be a bit pokey, you always seem to be a bit further ahead than the screen shows, making it occasionally difficult to know where to turn in an unfamilar area
- TomTom's status bar is configurable. It annoys the crap out of me that on Garmin, you're stuck with your speed being in the lower left corner, and arrival time in the lower right. These are not changeable. Why do I need my speed displayed, when I have a speedometer right in front of me? Wouldn't it be much smarter to display remaining time, an arrow indicating direction of next turn, miles remaining, or even a clock?
- They both deal with detours differently. TomTom gives you more options as far as dealing with rerouting and detours, but Garmin's ability to eliminate a specific TURN (not a street) is more useful than anything TomTom offers, IMHO
- Garmin doesn't have all the different voices available
- TomTom's motion is smoother
- Garmin has fewer issues with built-in GPS (at least on Mogul and Touch)
