I find Modo very awkward. It rarely does anything in a single click. If you want a sphere, you click on the Sphere icon and then click on more buttons. If you want to sculpt, you click on 'Sculpt' and then you have to set your brush settings or you'll just get nothing happening. This approach really makes a program a pain to learn because it forces you to study all the options right from the start.
I prefer a program to always use default options for its tools.
