I left OSX for Linux 5 years ago primarily due to the unbelievably lacking window management. Having come from Windoze land with the then, and perhaps still, excellent UltraMon, I could never adapt to manually reizing app windows side by side into grids, or context switching between layers expose-style.
The tiling window manager options on Linux are so good that I've dropped the desktop environment entirely (Gnome, KDE, etc.) and am just rolling with a TM, lightweight theme and icon package for a quite nice gtk3 look.
OSX wins in out of the box "just works" and bling departments, no argument there, but otherwise it holds no appeal, this bird has flown...
I started out with Awesome as well but switched to i3, get a huge amount of functionality out of a very straightforward config (read: low PITA/high reward factor).
Anyway, for a very nice gtk3 look you can try StudioFlat off of the Gnome Look site, and gnome-icons-brave via whatever your package manager happens to be.
The tiny xcalib package (100kb) is also worth grabbing, hook up to xbindkeys and you get screen color inversion _per monitor_, very bad ass, your eyes will love it.
