I use fish on all my machines at this point. It's nice to have really smart auto-completion. I know bash can do some of this if you configure it correctly but I'm all about reasonable defaults. I can't be bothered with lots of configuration changes on every machine I touch. One word of warning, and this probably applies to any shell, you should keep one of your sudoers on bash or sh. I've had a few occasions where something broke fish so when I logged into the machine via ssh I would see a few error messages and the session would terminate when the shell died locking me out of the system. I never figured out what broke fish in the first place but it's taught me the value of having a fallback user/shell for emergencies.
