I used StumpWM for a while, but switched back to i3, although I miss controlling my WM with Common Lisp. If StumpWM could implement i3-like window management, I'd be in heaven.
Stump's static window frames is what's kept me using it for so long. I hate how i3 and other dynamic tiling WMs reshuffle and resize everything as soon as you open a new window.
However I'm currently trying w9wm again; I have a slightly-hacked version that I've used on and off for about a decade and it's always fun to return to.
