I used fish for a couple of years and really liked it. But I recently learned that I can configure ZSH to have all of the same auto-complete and plugins that I loved from fish. Now I have all of the creature comforts I like, with POSIX compliance
I found that while fish has better syntax than bash for most things, the hassles with incompatibility or unexpected behavior brought me much more trouble than BASH's syntax ever has
The best reason to choose fish over zsh is that everything works so well out of the box that you stop messing with it.
I haven’t tweaked my shell config in 7 or 8 months now.
This is a different mindset from the giant zsh configs, “plugin managers” and other junk that is wholly irrelevant to using the shell. You’d think that fish incorporating a lot of functionality that zsh has would manifest as bloating fish, but, IMO the reality is that zsh’s “bloat” is pushed into user configuration and the user is tasked with making it work.
Another issue with zsh plugins is that they are incredibly slow. Oh-my-zsh makes every terminal feel like it’s running on another machine over ssh
I thought there was something in, like, Powerman10k or something, which managed to avoid that issue?
As for a replacement for oh-my-zsh itself, I had good experiences with zgen[1] but the fastest I've found is zim-fw[2] which produces acceptable start times for me[3].
