I upgraded from a Garmin to a Tomtom earlier this year.
The Tom tom is much quicker at re-calculating, and it's pretty accurate. The Live Routes feature is extremely useful (calculates the best route based on time of day, day of the week, so forth and history of traffic on that route). It also seems to 'learn' your preferential routes. This was the main reason I replaced the garmin with a tomtom - I couldn't find a garmin that offered the same sort of functionality.
However, my garmin had a speed camera database built in - tomtom want £15 a year from me for the same functionality, which I'm hardly going to pay.
