Not for everyone, but I love the completeness of the theme and the high contrast.

What do I mean by completeness? Usually with a theme there is one dialog box somewhere that's either unthemed, because it is in the default theme and doesn't match, or unusable, because the text is the same color as the background. Plus, out of all the themes I have saved, this is one of just a few that works out of the box with Firefox's new vertical tabs.
