I've had the bedroid theme and Dave pro 5.0 and the Dave theme is amazing. Fast functional and clean. Crappy thing is Dave took down the download link but a few of us have the files still for those who want it.

Miro2 is fantastic, followed by Iris (in grey). Miro is one of the few that has updated icons, but it always was one of the most beautiful themes. It doesn't seem like many are updating their themes for the latest OS. Calx's Real Icon2 has REALLY nice icons but we are waiting for the update.
It must get discouraging to the developers to have to keep adjusting their themes to the idiosyncracies of the updated OS. The newest development tool was supposed to be The Answer to theme develpment, but the extreme drop in both new themes and updated ones must mean it is a huge PIA.
