  Compare isn't quite right (although Garmin does have a really strong website now for working out http:\\connect.garmin.com ) they really should be accessed by how well they work together.  Again, another plus for Runkeeper is its ability to connect to my Garmin watch and download the run directly into my profile. I doubt the Nike site does, but ARS should have looked at this for RK and SR.  Like some of the other RK users - I don't care about a fancy/flashy app on my phone. Heck since I bought my Garmin 000 a couple of months ago, I haven't even touched the app (don't need it). What I care about is the quality of the website and the tools it has for reporting and reviewing workouts. For this, Runkeeper blows them all away!
