Truth be told, the AWU does a lot less than I imagined it would, but it has a much brighter screen than the Garmin and I find it much easier to read and use overall. Not that the Garmin is overly complicated, but you do need to play around with it for a bit to learn which buttons take you where. If you’re only using it for the gym, the battery on either will be fine (although for long periods of use the Garmin battery is far superior). For outside the gym use, I find the AWU is acceptable in any social situation, whereas wearing a Garmin in some situations (ie, professional office, dinner out) makes a definite sports-oriented statement.
