For my particular monitor, that’s most of what I would use on i3 due to size limitations. The issue for me is that splitting the screen in OSX is so clunky compared to i3.
I use Hammerspoon and I have got a modal dialog that I summon with alt-space. This shows me the keys I can press next, and some of them are to move the current window to specific positions and sizes, such as 100% of the height and 80% of the width, on the right hand side.
It's not the same thing as a tiling window manager, but I actually like it better: I can use the 80%x100% size for my browser and keep a terminal on the left hand side. Then I can browse HN while still watching the terminal for output. When there is output in the terminal, that's a trigger for me to switch.
