Too many choices!

I have been training with the Garmin 305 quite a bit now. Today was the first time using the speed and cadence sensor. The amount of information that the device logs and the website (MotionBased.com) compiles from external source is pretty amazing!

Surprised to see that it rated my course today at 4.x out of 5.0 in terms of difficulty.

I am kinda confused with which websites to use...motionbased, trainingpeaks, mapmyfitness sites or bimactive.com! MotionBased has pretty cool animation of your workout...
