I think once you get used to a tiling window manager, like force yourself to use it for over a couple weeks, it's very difficult to go back. Somewhat similar to vim.
Personally, I have 2-3 external 32" 4k monitors and I want to maximize the real estate that's used, tiling wm (specifically i3 in this case) makes it very easy to move windows around, to switch between different screens, to move screens between different monitors quickly. Dragging a mouse across that relatively high screen real estate is a huge pita without i3.
