It's really handy if your "window manager" is actually in your terminal (say, you use tmux). Otherwise you've got two layers of "window manager" to deal with—your terminal multiplexer, and your actual window manager. Why might one use something like tmux instead of relying on Rectangle or a tilling window manager or what have you? 1) The terminal is far easier to gain access to cross-platform than any GUI window manager, so if you can keep most of your workflow in the terminal, you can work just about anywhere. You get it out-of-the-box basically everywhere but Windows (assuming we mean a Unixy terminal, here, not cmd or powershell) but it's very easy to gain access to a unixy terminal there, too, these days. 2) Maybe you are constrained to the terminal for some reason, as in the case of a remote server that doesn't have X installed.
