Any runners in here have either of these? I have the nike + sprotsband, use it about every day, but its not an accurate tracker as Garmins GPS watch.

A watch that tells you how far you've run is 300 dollars. Nike+ wins by default.

Nike+ no question, all prices considered.

Ive used the Nike + for about a year now. I like it, but the damn accuracy, speed thing worries me. I am marathon training so this stuff is all rather important to me.

The garmin watch looks/is cool though. If you can afford to shell out 300, and it's important to you - just do it. (sorry nike)
