I also am a tiling window manager man and tried that a few years back (as well as everything else on the market) when I had a mac from work, unfortunately, without real support from the OS, these are all just poor mans windows managers and can't compare to the real thing. I gave up trying to use any of them and ended up installing a virtual machine where I could actually use one.

I'm a gnome addict. If you ever asked yourself "who are they building this monstrosity for?". That would be me, it fits my exact preferences in a workflow out of the box. Unity irritates me to no end, and my wife's mac is almost unusable for me which she greatly appreciates.

Not sure why you're being down voted, I use Amethyst and love it.
