I've been using spectacle[0] for a while and happy with it

Seconded - this is the first thing I install on any new Mac I get my hands on.

I have been using Magnet [1] for a long while and although it is not as flexible as Fancy Zones appears to be I am very happy with the extra functionality it provides.

Yeah keyboard shortcuts and tiling are a good way to multitask without having to think about window placement. Just specify which zone you want the window in and let the WM do the resizing work.

- You probably want to turn on 'On Override Windows Snap hotkeys (win+arrow) to move windows between zones'.

- Default zone is boring, I like 'Priority grid' which is two thin columns and a thick one.

After a while you don't really think about window management.

I've been using Yabai[0] for a few months and am generally pretty happy with the i3-like experience on macOS.

If you're willing to put some time into configuration, check out chunkwm (which is apparently being replaced by yabai, which I haven't tried). Its the closest I've gotten to a true tiling window manager on OSX, not without its quirks, and requires some work to get the way you want it, but it's at least something.

Though it isn't as fancy when creating custom layouts, I'm very happy with Amethyst[0] on macOS.

Check out better snap tools. It’s not free, but it’s kept updated and works remarkably similarly to the tool listed here.

Multiple desktops are pretty useful though.

They are, but it's not exactly the same. I want to customize my current Desktop with multiple windows arranged "just so."

Mulitple desktops with windows nicely arranged on each is even better.
