I also choose to not disable SIP. The only thing that I miss is being able to disable animations, besides that I'm using it just fine, not as good as i3 but good enough for me.

the one actual thing that slays me about OS X is the workspace switch delay. Everything else is on the range from bad-but-tolerable to great, if I could just disable that one thing I'd love it so much more

I’m using it too, but it is very unreliable. I need to restart the program often once a day.
