I looked at both. The thing that sold me on the Garmin 60csx was thebetter receiver to lock on to satellites in heavy cover. In the past I have had issues locking in under a heavy canopy, not any more. Works great and I am very happy. I compared it in the field side by side with a friends 60 or 60c I don't remember whichand sure enought there was a noticable difference in the time it took to get a reading.
