As another commenter pointed out, while Fish has some nice out-of-the-box features, they’re all achievable in Zsh with a few lines of plugins. And did you know Zsh has a short for loop? Along with fantastic plugins like fzf-tab, I don’t see a reason to use anything else right now. Though, I’m keeping a very interested eye on Nu shell. They’re doing a lot of stuff right, and I expect it will become a very useful scrip…
That said: what do you like about Nu shell specifically?
