I'd go with the Garmin (and probably will) due to my experience with their Streetpilot Range which are bloody good (£500 mind, so they should be).
The Garmin units I've used have clearer maps and are often more up to date than the TomTom ones. Oh, and they will also say 'Turn left onto x Road in 100 yards' rather than 'Turn left in 100 yards' as with the TomTom. Quite handy if there are multiple turnings in close proximity, as you don't have to take your eyes off the road.
Oh, and with the Speed Cameras, if you are using it to help avoid points (aren't we all? lol) then I'd subscribe to a service where you can download updates, rather than relying on the preinstalled list.
