I see pros and cons to both the Sawstop and the Whirlwind designs, I'll

having an advantage when it comes to contact with a stationary blade.

I don't see either having an advantage either if you drop the blade on
your foot on the way to the saw...that covers the case where the blade
is not stationary.
