For better pretty much everything, one may wish to try zsh. It's pretty much a strict superset of bash, but better.
There is one aspect in which it's significantly worse, though: it's fiendishly difficult to configure and understand. I just use configs provided by others, which is not ideal but works.
bash (with all features) is also a strict superset of bash (with default configuration that people think is all there is to it, especially if they use macs [1]), but better.
[1] If you are using a mac and haven't installed a newer copy of bash you're using a version that's nearing on 10 years old and does indeed mostly suck.
