I have used fish for a few years and quite liked it, but ultimately I think using zsh with oh-my-zsh or similar bundle is better because of bash compatibility.

I think if one only ever uses their own computers fish is better, but having to switch contexts, having to have different configurations and so on is a pain and not very productive.

I recently moved from bash to fish. Re-training is was easier than I thought, especially not having to tap Ctrl+R every time I'm looking in the history (that one was hard wired). I wrote about my migration here:

One thing I haven't touched in my article: globbing behaves differently than the default, which means you have to quote your '*.ext' arguments when using find for example. This is fairly well documented: https://fishshell.com/docs/current/index.html#expand

I very rarely move back to bash, so I consider this migration a success :-) If you haven't yet, should try it !

I know I was... well up until my 2008 MacPro died last month and I switched to Linux (ain't nobody I know gonna afford that new MacPro on their own).

Now I use Fish Shell on Linux and it's fine for what I usually do.
