I used to used zsh, like I still have have karma moving up on stackoverflow as I answered my own questions on some obscure configuration fine tuning. But currently I'm more in a "give me the thing that work off the shelf" moment, so I take fish and don't plan to either look back.

Byobu with tmux as backend is my go to solution if I want a multiplexer, for what it worths.
