I find myself customizing fish way more than I ever did with Bash. Writing custom completions is easy and I find the scripting syntax a lot nicer. Combining the two is really powerful. Granted, fish ships with a ton of completions out of the box so you may not need to write your own.

And if some tool you use doesn't have completions, writing completions for fish are infinitely easier than bash

If anyone is interested in comparing and contrasting, the Standard Ebooks tooling has the same completions for:

Bash: https://github.com/standardebooks/tools/blob/master/se/compl...

ZSH: https://github.com/standardebooks/tools/blob/master/se/compl...

Fish: https://github.com/standardebooks/tools/blob/master/se/compl...
