Both the 60csx and HCx units have a feature called “Tracklog” this will give you an accurate reading of the distance you’ve travelled, per track. The units have on average 10,000 track points, and can save up to 20 different tracks. You can also use the calculate the distance between 2 waypoints, using the area calculation feature.

Most GPS units have drift issues The odometer in the HCx should be find if you are driving or cycling with it. For walking/hiking it isn't really neccessary.

Sorry - accidently posted that twice

If you're just using it for geocaching and won't be doing any city/street navigation you'll probably want to go with the Vista HCX. It's much more compact which is good for portability. The Vista has the same GPS functionality as the 60csx (barometer, alimeter, compass) but has fewer waypoints and track points. Hope that helps!
