I'm on Windows 7 Aero. I don't know if it matters or not, but i'm not able to read the text very easily on here on either theme, unfortunately. It's because of the textures on the tabs that are appearing when I have multiple tabs. The selected tab I can read, because it's a solid red or cream color, depending upon the theme. Other than that I really like both of them. I'd like to use the Heaven theme, but I need to be able to read the text in my tabs. They do look good though!
