Much better than any software before. Orienteering in a Swiss forest. Difference between Garmin and Leikr is within < 1%. The track looks so much better than before. However, there are still some jagged parts.http://www.endomondo.com/workouts/289231979/8104552
PS: I got a replacement watch a few days ago. So I cannot say whether the improvement is only due to the software, due to the hardware (i.e. the old being defect) or due to both.
