Honestly, it’s just another shell. Both Bash and ZSH happen to be mostly POSIX compliant, so stuff that works for Bash tends to work with ZSH too. For me it’s mostly just about the stuff I can add to it - I use the antidote plugin manager to get additional autocomplete, syntax highlighting, suggestions, async prompt updates, that kind of thing.
Man, I’d settle for something that doesn’t cost an arm and a leg for a shit box with terrible range half the year when it goes under freezing temps…
