Ok.. for those who use both the Genesis and Sportsman... hatch rates?

What I am trying to figure out is if the Sportsman is actually better at incubating than the using several Genesis units.... having several means a failure is more localized... but there is the convenience issue.. and cost per capacity.... what i need to have a handle on to make up my mind are some relative performance stats.... this would be for chickens... thx!
