I was able to adopt fish shell and get many features from bash that were provided from plugins. I prefer the more “stock” shell configuration for easier maintenance across computers and over time, and a less complex dotfiles project. https://github.com/andyatkinson/dotfiles

On a team I limit my fish shell use to my own machine though, and would use bash for scripts to share with a shebang line. I also switch to a bash shell when needed.
