feel free to list other window managers you’ve used.
I have been happy with bspwm, but considering trying something else. I love its simplicity and immense customizability. I like that it is shell scriptable, but it is not a deal breaker feature for me.
I like how the binary split model makes any custom partition possible.
herbstluftwm - because it just works and does not try to think for me;
The configuration is a shell script using herbstclient to talk to the wm process, that’s a plus for me, too.
