I don’t like the gradient-heavy look. I’m more of a fan of flat desktop themes. Additionally, I like dark top bars and light content sections. Here are my three favorites, viewed using lxappearance:
BlackWhite by lyrae
FlatStudio by trastes
Siva Flat by nale12
All three are in the AUR (I actually maintain blackwhite, and messed it up the first time).
And if anyone is curious, the font is agave.
