I do wish there was better bash compatibility though, it keeps me from using fish on remote hosts, and some of my work tools are not fish compatible. I usually just switch to bash for a bit, but then I don't have my normal completion, history, git branch identification etc that comes out of the box with fish.

I'm a huge fan of sane defaults. Fish strikes a great balance here where I feel zsh requires a larger minimum amount of effort to be comfortable.
