However, what I appreciate most is altitude and this is what sets the watch apart.

Personally, I prefer GPS-derived altitude since the range of accuracy is higher than the range due to barometric pressure differences.

My phone was off 450m on the same run)Also, since the GPS is so good, the instant pace is also great (not as great as with a footpod but comparing to other gps units is way above)The watch has good amount of customization and shows really solid info on the watch itself after a workout
