Rate These Keyboard Layouts

I am looking for some user input on how good you think each of these keyboard layouts is. Please rate each layout based on the amount of effort you think it takes to type. If you want to know letter frequency, you can find it here. See here, here, here or here for some ideas on what makes a good keyboard layout.

You do not have to answer every question. Any answers are appreciated. Please do not answer any questions more than once. And, of course, feel free to leave comments.
