I'd add an 11th point to expand on #1: supports a very wide range of movement speeds, movement force/torque and movement precision.

Take the elbow joint and the muscles it's connected to. It supports very fine precision, slow speed operations as well as high speed but at the same time the same operation at high speeds - say, lifting yourself up on a horizontal bar, assuming adequate strength you can either do a slow or a fast lift, and both at enough precision and torque to prevent your body mass from impacting to the bar which is another feat in itself.

Now try to replicate that with a classic mechanical mechanism, you'll always lose either precision, speed or torque.
