For me it's bspwm. It's closer to i3 in simplicity, but has some dynamic tiling functionality that "cooler" WMs do. It's very modular, the documentation is grea

For me it's bspwm. It's closer to i3 in simplicity, but has some dynamic tiling functionality that "cooler" WMs do. It's very modular, the documentation is great and you can get started in just a few minutes. "power users" or people who are willing to get their feet wet with code can check out XMonad (Haskell), AwesomeWM(Lua), and Qtile(Python) as well. DWM (C) is a popular choice too nowadays and is rather nice, but I can't bring myself to care about terribly documented software that justifies it by saying "we'd like our user base to be small and elitist."
