I've tried Modo's 30-day trial version again about a month ago, and still couldn't get used to it. But that's predominantly a personal thing, because I am way too used to Blender's workflow, keyboard shortcuts, menus, etc.. Switching between the workflow, functions and keyboard keys of four 3D applications (Blender, MoI, ZBrush and Keyshot) makes my head spin enough already. :)
