The "execution" seems better at first blush. The documentation is short and to the point, which means it's something which would lead me to use it, especially since I still haven't figured out how to easily deploy most of the others you mention. The ability to have go produce cross platform binaries would ease a lot of deployment issues as well. Along with distributed logging, it's something I'll probably try using. Unless any of the above have advantages, primarily in the ease of use category.
