Literally priced Lutron Radio RA2 and Control4 lighting (not Essential line) yesterday for a new project. Lutron was 35% higher.
Unless there is existing Lutron lighting in the project, our view is it makes little sense to choose Radio RA2 over Control4 lighting these days when you consider the cheaper price, no need to integrate third party system which introduces potential for problems (for any third party integration), faster integration, Zigbee mesh, better / more flexible keypad programming and more choices for LED / backlight colours.
